Retaining Structures Design And Pumping Test Research For Juyuanzhou Station Foundation Pit Retaining Engineering Of Fuzhou Rail Transit Line 2

In this paper,the design method of the retaining structure in the current project is taken into account in the foundation pit of the Orange Park Station of Fuzhou Rail Transit Line 2,and the type of support is evaluated to determine how the various support types are suitable Kind of situation.Based on the actual engineering of this paper,considering the depth of the foundation pit,the groundwater level and the distribution of the adjacent buildings,the supporting type of the structure is determined and the reasonable design is carried out,and the structural reliability checking,And the pumping test of the foundation pit has been studied accordingly.Combined with the relevant factors influencing the design of engineering structure support,the foundation pit retaining structure of Orange Garden Station of Fuzhou Rail Transit Line 2 was calculated and analyzed.For the various parts of the envelope of the internal forces,deformation and stability analysis,is the application of professional computing software,such as: in the 7.0 and Tong Ji Star FRWS5.0 and other software,and the structure of the bottom of the uplift and overturning done in detail The results show that the strength of the components in the support structure,the internal force deformation of the foundation pit structure,the stability of the seepage resistance,the anti-overturning stability and the surface subsidence are all satisfied with the design requirements.According to the higher groundwater level of the foundation pit,the difficulty of precipitation and the large amount of surrounding land subsidence,the waterfall test inside and outside the curtain,the recovery test of the recharge test and the settlement observation of the surrounding buildings are carried out to provide a reliable reference for the precipitation scheme.
