Circular Diaphragm Wall Shell Finite Element Simulation And Analysis

According to the three-dimensional effects of the circular diaphragm wall is so remarkable, this article used the three-dimensional structure modeling method to carry on the simulation analysis.The model considered the circular diaphragm wall and circular lining as elastic material, and the soil as D-P model. The soil and the circular diaphragm wall to be separated as entities element, and the circular lining as shell element to simulation. Circular lining as a shell element attached to the circular diaphragm wall inboard. Even in the analysis to determine the reasonable thickness of the lining shell, we can only modify tactical parameters without a new model.Model calculations show that in ideal conditions the circular diaphragm wall "the Arch Effect" could well limit the side deformation of the circular diaphragm wall, The circular diaphragm wall's stress of the Circle direction is much greater than its vertical stress. "The Arch Effect" of the circular diaphragm wall can greatly reduce the side deformation of the structure.At last, this article depicted the prospects of the three-dimensional shell element analysis methodology of the circular diaphragm wall, and also indicated the prospect of the method.
