| 摘 要： | 基于优化桩型的观点,将柔性桩和刚性桩组合,刚性桩和散体材料桩组合,形成多桩型组合桩复合地基,充分发挥了柔性桩、刚性桩和散体材料桩的优点,弥补了单一桩型在地基处理中的不足。通过对现有多桩型组合桩复合地基承载力计算方法进行分析,建立了多桩型组合桩复合地基极限承载力可靠度概率分析模型。用JC法进行可靠度计算。通过刚柔组合桩复合地基实例,分析了随机变量的变异性对可靠性指标影响。

| Abstract: | Based on the optimized pile viewpoint, the flexible pile and the rigid pile, the gravel pile and CFG pile are arranged in a group as compound piles, which utilizes their merits and avoids their shortcomings. Through analyzing the calculation methods for the bearing capability of composite foundation with multi-type piles, the reliability probabilistic analytical model of the bearing capability of a composite foundation with multi-type compound piles are set up. JC method is used in the calculation of reliab... |
