摘　　要：Economic and social progress has led to an increase in the number and quality of construction projects. It has become an important topic of concern to solve the difficulties and risks of shield-driven construction of weathered diorite in the whole section. Relevant personnel need to effectively analyze the risks of shield-driven construction through special strata, and on this basis, put forward corresponding solutions. Based on the analysis of the selection of the shield machine and the shield machine crossing the special stratum, this paper strengthens the research on the selection of the shield machine, carries out in-depth research on the shield machine advancing in the special stratum, and puts forward the risk control measures, which provides the basic information for the subsequent similar engineering construction.
