摘要
本文针对剪切模量沿深度线性变化的半空间,提出了桩受垂向力作用时桩土相互作用的一种简便积分方程法。该方法应用集中力作用于剪切模量沿深度线性变化土介质的基本解以及桩的基本解,分别建立起桩和介质两组一维非奇异积分方程,再使用位移相等和应力平衡条件求解联立方程而得到应力和位移。计算结果表明该方法合理有效,并具有省时、精度高、简便的优点,是分析桩在不均匀介质中相互作用的有效方法。
A simple integral equation method for the interaction of the pile-soil applied by the vertical load on pile is presented in this paper for the purpose of the half space of shear modulus varied linearly with depth. This equation method establishes two sets of nonsingular integral equation of one dimension respectively in the application of the fundamental solution of conccntrational force at the medium with shear modulus varied linealy with depth and the fundamental solution of the pile, and the stress and displacement are obtained further in the application of the conditions of compatible replacement and stress equilibrium to salve the simultaneous equation. The calculated results show that this method is reasonable and effective, and possesses the advantages of time-saving,high accuracy, simplicity, and convenience. This method is an effective method to analyse the pile interaction in the nonhomogencous medium.
