Abstract
Based on the theory of progress control and risk management, this paper systematically sorts out the progress risk of Beijing Daxing International Airport, discusses the general schedule and progress risk identification model and its approach, and constructs multi-level early warning and dynamic monitoring methods for progress risk. Meanwhile, the method for general schedule and progress risk management of large-scale airport projects is also studied. The practice of early warning and control of the general schedule and progress risk of Daxing Airport project has achieved good results, which provides support for the comprehensive progress control of Daxing Airport project, and guarantees the realization of the target completion time of general schedule.

Abstract
From the analysis of different time stages of flight planning optimization, flight planning optimization can be divided into three aspects: static flight planning optimization, flight planning dynamic feedback optimization based on flight delay prediction, and flight planning dynamic adjustment based on airport collaborative decision -making (A-CDM). Then, it analyzes the static scheduling and optimization of flight plans from the preparation links of flight schedules, aircraft type assignments, and flight frequencies; then uses the optimization method of delay spread prediction and data mining prediction to analyze the correlation of flight plan dynamic feedback optimization based on flight delay prediction the study. Finally, according to the complexity analysis of flight plan optimization, the development trend and future research directions of flight plan optimization are given.

Abstract
With the rapid development of China's urbanization process, the original transportation plan cannot fail to meet the needs of urban economic development, and the transformation and upgrading of the urban transportation system is imminent. Urban rail engineering has become the only way to solve traffic problems in major core cities. However, conflicts between subway shield tunnels and existing building foundations occur from time to time, especially when some important buildings and public facilities cannot be demolished, underpinning technology is required. This paper relies on the Shijiazhuang Metro Line 2# underpassing the urban overpass special-shaped slab beam construction and bridge project built in 1994, combined with the past pile foundation underpinning and current intelligent construction technology, in the multi-support prestressed concrete special-shaped slab beam substructure pile foundation Intelligent pre-supporting technology is adopted in the underpinning construction process, which solves the problem of synchronous control of multi-supporting special-shaped slab girder under complex environment, and ensures the safety of construction and bridge operation.

Abstract
In recent years, urban development, population expansion, and water pollution have become more and more serious. The main cause of reclaimed water pollution in Wuhan is that the combined drainage system is still retained, which makes the overflow pollution of the drainage system and the problem of regional waterlogging particularly prominent. The use of a sewage deep tunnel system to replace the traditional confluence system can basically eliminate overflow pollution. At the same time, applying value engineering to the decision-making stage of sewage deep tunnels for scheme comparison and optimizationcan effectively reduce costs, increase revenue, and enhance use functions.

Abstract
In the process of building construction, the optimization of the construction scheme has always played a great role in saving construction costs, reducing construction risks and speeding up the construction progress. This paper studies the optimization of the implementation plan of the deep foundation pit earthwork excavation stagein the actual case, and analyzes the results of the optimization of the plan, so that the optimized new plan can accelerate the construction period and save money while ensuring the project quality and construction safety. The construction cost has played a significant role.

Abstract
Many bridge piers were built in the Coastal Interconnection Project of the Ningbo Section of the Hangzhou-Ningbo Expressway Double Line. Affected by the tides at the bridge site, the high pile caps are constructed using a suspending cofferdam without a bottom cover. Based on the consideration of various factors such as construction difficulty, safety, cost and construction period, etc. A cement structure is generally adopted as the floor of the suspended box cofferdam. The steel-concrete combined hanging box cofferdam without bottom cover adopts the structure of steel wall plate and prefabricated cement floor, and the partition wall plates are connected by bolts. The steel-concrete composite suspending cofferdam adopts the prefabricated bottom plate and wall plate. The construction sequence is listed as follows: First, weld the load-bearing corbel on the steel casing, and then hoist the prefabricated bottom plate to the steel casing corbel in blocks. Pour the wet joint between the prefabricated bottom plate and install the side plate. After that, pour the cushion after welding the shear plate. Finally, carry out the construction of the cap. During the construction of the project, the connection method between the wall plate and the bottom plate was optimized. The connection of the fine-rolled rebar hanger rod was changed to the steel bar pair pulling, which improved the construction efficiency significantly.

Abstract
In Taos barrow of jade grinding rail tunnel engineering ii, of rich water karst region slipped in weak rock tunnel collapse mechanism and treatment technology for research, slipped through the establishment of the tunnel surrounding rock collapse mechanics analysis model, the theoretical calculation and finite element calculation software simulation method of combining the, constraints of the tunnel to slip down position at the beginning of surrounding rock and the structural stability analysis, According to the analysis results, the corresponding treatment measures are put forward. The results show that the settlement value of surrounding rock vault is 84.7mm, and the horizontal convergence value of arch waist is 167.4mm. The deformation value of surrounding rock is large, and it is easy to collapse. The plastic zone of surrounding rock mainly occurs at the junction of upper and lower steps on the face of the face, and the maximum plastic strain is 6.63×10 -2 . The arch waist of the primary support structure is prone to stress concentration, which should be reinforced during construction to prevent instability failure. According to the actual situation of tunnel construction site, combined with the finite element calculation results, the treatment structure of concrete filling combined with small pipe reinforcement was used to treat the tunnel slide collapse section. The treatment effect of tunnel slide collapse section was better, which provided a reference for the treatment of the same situation in the subsequent construction section.

Abstract
In recent years, with the rapid development of subway and underground comprehensive pipe corridor, the problem of close connection between underground structure and existing subway section structure is often encountered in engineering construction. During construction, the newly built underground structure will disturb the stratum, easily cause the additional displacement deformation and internal force change of the existing tunnel structure, and then lead to safety accidents. Therefore, it is particularly important to analyze the influence and safety evaluation of the new construction on the existing subway structure. This paper takes the construction of new underground power pipe gallery close to the existing subway section as an engineering case. The influence of adjacent construction on the existing structure is analyzed by three-dimensional finite element method, and then the safety of the existing structure is evaluated through deformation prediction, internal force analysis and bearing capacity checking calculation, and some construction safety protection suggestions are put forward. It has a certain reference for similar proximity projects.
