摘要
复合地基理论被广泛应用于处理软弱地基工程实践中,而加固桩体的有效桩长是复合地基理论中需要考虑的重要问题之一。文章从加固体的荷载传递规律和应力扩散理论角度出发,应用弹性半空间体内任意点附加应力Boussinesq解,求出有效桩长的计算公式,并结合工程实例介绍有效桩长在工程中的应用。
The theory of composite foundation is widely applied to dealing with soft foundation in engineering, and the effective length of a pile is a key issue. According to the load transfer law of piles and stress dispersion mechanism, the formula for calculating the effective length of a pile is derived by using Boussinesq's solution for the additional stress at any point in an elastic semi-space. An application example is also given.
