摘　　要：有效桩长是柔性桩复合地基设计时需要考虑的一个重大问题。已有的柔性桩复合地基有效桩长计算方法都难以准确计算有效桩长。本文基于M ind lin位移解和位移协调条件,通过一定的假设和公式推导得到了有效桩长的计算方法,并与其他的一些方法的结果进行比较。Effective pile length is an important problem that should be thought about when making a design of flexible piles composite foundation. It is very difficult to calculate the effective pile length for the methods which have be used by mostly engineers. Based on Mindlin solution and displacement compatibility equations, the effective pile length is calculated herein and the solution is compared with the other solution in this article.
