FEM Analysis of the Corrosion Residual Bearing Capacity of Steel Sheet Piles Link-Banked Structure of High-Piled Wharf

摘要

Steel sheet piles link-banked structure as part of high-piled wharf is very important for limiting the deformation of bank slope. The problem that induced by the interaction between filling and steel sheet pile is usually concerned as that of passive pile-soil interaction. Corrosion and damage have presented in the steel sheet pile link-banked structure of Tianjin Port 9～11 wharfs and Its impact to the structural safety is thus very urgent to be studied. The FEM software ANSYS is used for the analysis of the interaction of steel sheet pile and soil model in the article,then the two conditions of steel sheet pile when it is normal and corrosion have been simulated,and the force status of steel sheet pile and distortion of link-banked structure and soil were obtained. It can provide evidence for judging steel sheet pile safety.
