In deep silty soft soil

bored piles combined with jet-grouted anchor cables are used as the retaining structure

supplemented by cement-soil mixing piles for passive zone reinforcement. If the construction process is not properly controlled

the foundation pit is prone to significant deformation. Taking a case study from a certain foundation pit project in Dongxihu District

Wuhan

this article uses numerical simulation to simulate the collapse process of foundation pit

attempts to analyze the reasons for excessive deformation of this foundation pit

and puts forward suggestions for similar foundation pit projects

which has certain reference and guiding significance.
