Abstract
The design of deep and large shaft excavation and support is not only related to the safety of personnel and machinery during construction, but also directly affects the safe and stable operation of the long-axis deep well pumping pump station in the later period. Therefore, the design of the surrounding rock support of the working shaft is very important. This paper makes full use of the advantages of Midas GTS NX geotechnical finite element analysis software and FLAC3D finite element analysis software to analyze and calculate the primary and secondary support of deep and large working shafts, verifies the rationality of the primary support measures, and provides specific design parameters for the secondary support design, which has a good practical guiding significance for the actual engineering design.
