2-D Finite Element Analysis of Prestressed Anchorage Sheet-Pile Wall

With 2-D finite element method (FEM), the moment and displacement of metope piles, the stress and displacement of interface between anchorage pile and surrounding rock, the settlement and earth pressure of filling soil, and the internal force of anchored cables are calculated in six typical conditions of construction. And the calculation results accord basically with those of field observation and other numerical methods. The results show that the the moment and displacement of metope piles can be decreased effectively by the use of prestressed cables.
