Force and deformation analysis on the fully recovered support system of pressure anchor cable and steel module

Abstract In order to overcome the technical defects of traditional foundation pit support technology, such as complex serious pollution, waste resources, and obstruction construction surrounding underground structures, fully recovered deep system pressure dispersion anchor cable steel module is designed. The force compression deformation modular tested on-site. test results show that: (1) whole process excavation slope roof immersion stacking safe, which verifies correctness design modular; (2) soil restraint effect at action recoverable obvious, prestress loss between 11.7% 15% under continuous monitoring; according axial cable, earth acting on calculated, are consistent with calculation Terzaghi-Peck mode; (3) According strain module, corresponding stress its value plate fixed in four corners pressure.
