Analysis and Damage Inspecting Technology of Supporting Structure in Deep Foundation Pit Construction

In order to reduce the supporting failure rate and to improve the performance of damage inspecting of supporting structure in deep foundation pit construction, the structure analysis based fractional algorithm and damage inspecting system is proposed in this paper. Theoretical analysis of static and dynamic structural responses of the deep foundation pit structures after repairing and strengthening are adopted by using SAP2000 Ver. 14.2.0 software. The results of theoretical analysis of static structural response shown that the values of tensile stresses are decreased about 50%, and the values of vertical deflection are decreased comparing with the values before strengthening, indicating that the strengthening methods are effective to improve the structural performance of the deep foundation pit structures.
