Abstract:

foundation coefficient method is a common method for calculating internal forces of a elastic anti-sliding pile. Based on coefficient “m-k” method, the counterforce load method is presented to calculate the internal forces of a whole pile. The corresponding formula are derived in detail. The calculation program of internal forces for a whole pile is designed with Matlab. The pile can be analyzed as complete entity. It is not necessary to divide the anti-slide pile into loading segment and anchoring segment by the sliding surface like the tradition methods. Compared with the finite difference method, the presented method does not make use of the continuity condition at the sliding surface and the iteration and test calculation. An example shows that results coincidence well comparing the traditional method can be obtained. The results of figure treatments by the program can optimize the construction design of anti-sliding piles; and it demands very short time for the calculation and can improve the calculation efficiency.

Key words: elastic anti-sliding pile, whole pile internal force, foundation coefficient “m-k&rdquo, method, counterforce load method
