Finite element analysis for slope stability with multi-braced retaining wall through reduction of strength parameters

The application of two dimensional(2D) finite element method based on the concept of reduction of strength parameters for the slope stability problems with multi-braced retaining structure was discussed.The effects of factors such as embedded depth and the braced conditions of retained structure were investigated.The results of the finite element method were compared with those computed by Ordinary Method of Slices and Bishop’s Modified Method.It was shown that braced conditions and embedded depth of retained structure was also essential to slope stability with multi-braced retaining structure.It was also shown that the finite element method based on concept of reduction of strength parameters was reliable and effective and could consider easily the effects such as embedded depth and the braced conditions,and the obtained results provided reasonable warranty for confirming braced and embedded depth of retained structure.
