OPTIMUM DESIGN OF INTERACTION BETWEEN PILE AND PLATFORM CONSIDERING VERTICAL STIFFNESS OF PILE
考虑桩竖向支承刚度的桩-承台共同工作的优化设计

Based on the influence of difference of the diameter or length of bored pile on the vertical stiffness of pile,an analytical optimum design model of interaction between pile group and bearing platform is proposed with the vertical stiffness of pile into account. The bearing capacity of each pile could be fully utilized and the interacting characteristics of pile and platform is verified by means of engineering practice.
