Study on Deformation of Underground Continuous Suspended Diaphragm wall Based on Minimum Potential Energy Principle
In order to solve the problem of continuous suspended diaphragm wall,a new method for calculating deformation of underground suspended diaphragm wall is proposed based on the minimum potential energy method.The reliability of the method is verified by comparing with the simulated and measured horizontal displacement of the diaphragm wall in an engineering example.Moreover,the influence factor of pit corner is introduced to consider the influence of pit corner on the deformation.The influence of disturbance,unloading and stress redistribution on the mechanical properties of the rock shoulder during excavation will further increase the deformation of the continuous wall,so the stability of the continuous hanging wall can be increased by adjusting the width of the rock shoulder.
