Calculation Method for Deformation of Foundation Pit Support Structure under Asymmetric Load
In view of the displacement characteristics of asymmetric loaded foundation pit,based on the elastic foundation beam model,the overall calculation model of asymmetric loaded foundation pit is proposed by connecting walls on both sides by supporting axial force.Through the solution formula calculation of the earth pressure of the limited width soil,the formula of the wall-soil friction angle and the internal friction angle of the soil displacing with the wall is introduced,and the coupling effect of the wall deformation and the active earth pressure outside the pit is considered.According to the calculation model of asymmetric load,the deformation control equation of support structure under asymmetric load is obtained.Finally,the algorithm is verified by practical engineering.
