| Abstract: | Based on the limit equilibrium theory,a calculation method of safety factor and anchor force of the retaining wall with pre-stressed anchor was deduced under the seismic action.With the help of finite element software ADINA,the numerical simulation and experimental validation had been done during the whole process under excavation on the side slope.The analysis of interal force and displacement proved that the method matched quite well with the practical case.As compared with the schemes in the practical pr... |
