摘要
通过与刚性基础-桩群-土体系的比较,对级配碎石水密法填筑路堤-土工格栅(含基底缓冲层)-现浇薄壁筒桩复合地基体系提出了一种准刚性基础-桩-土共同作用的非线性分析近似方法。计算表明,该方法简便、实用,能较好地反映桩、土非线性特性对路堤受力变形的影响。
Based upon the similarity of the rigid foudation-piles-soil system with the embankment after water jet-geogrid reinforcement-composite foundation of cast-in-situ thin wall concrete pipe pile system, a kind of approximate method for nonlinear collaboration analysis of quasi-rigid foundation-piles-soil system is presented. Through the calculation, it is shown that the method is concise and effective.
