IMPROVEMENTS AND APPLICATIONS IN "K" METHOD OF INTERMAL FORCES CALCULATION OF STABLLIZING PILES

Some improvements are made on the traditional K method about intemal force analysis of the stabi1izing pile against 1ands1ide. For ex-amples, a universal coordinate including above and below sliding surfaces is established. The pile is considered as a whole body. The continuity of inter-nal forces and displacement is assured through reasonable supposition. Meanwhile, the well - known mathemaic software MATLAB is used to design aprogram of K method. The program can be applied to all sorts of distributions of lateral force and soil reaction as well as rigid or elasic stabilizing piles.Compared with the traditional method, a calculated case shows that this method can effectively improve calculation speed and precision of internal forcesof stabilizing piles. Reasonab1e visual resu1ts of calcu1ation can be obtained. The visual figures are helpful to optimize the structural design of stabilizingpiles.
