摘要
文章对现行复合桩基设计理论进行了分析研究,确立了复合桩基的临界工作状态和主要失效模式,对复合桩基承载过程中的沉降进行了分析与计算,并对其进行了随机性分析。运用可靠度理论建立了以沉降控制为目标的复合桩基可靠性指标计算方法,结合工程实例,探讨复合桩基承载过程的可靠性指标变化规律,取得了一些有实用价值的结果。
In view of the problems in the design of composite pile foundation,the critical working condition and the main failure models are studied. The settlement of composite pile foundation is calculated and analyzed with the stochastic theory. By setting the settlement of composite pile foundation as the control object function, a reliability index method is established with the reliability theory. The regularity of the reliability index varying with the loading change is also investigated with a practical example. The obtained results are useful in practical engineering.
