刚性承台—桩群—土共同作用的两种迭代算法

Two Iterative Methods for Cap-pile-soil Interaction Analysis

针对现有承台-桩-土共同作用分析方法存在的问题，引进了两种迭代算法，通过理论和算例的比较分析，说明了这两种迭代算法用于承台-桩-土共同作用分析的特点和适用性。使用迭代法可避免满阵矩阵，大大节省计算内存，能在微机上实现对实际工程的共同作用分析。

In the analysis of cap-pile group-soil interaction, two iterative methods are used to solve some problem of convetioal analysis. Through computing a numerical example theoritical comparison is made between direct method and iterative method. It is shown that the iterative procedures can avoid the use of the full Populated matrices and greatly save computer core memory. Therefore, the methods allow the use of small computers in solving many practical soil-structure interaction problems.
