摘要
研究了复合桩基承载力可靠性分析的方法 ,这对复合桩基的可靠性设计将起到积极的推动作用。采用复合桩基承载力计算公式Pu=I(nPp+Ps)来计算复合桩基的极限承载力 ,并通过实例计算 ,分析确定了承台底土及桩体极限承载力的均值和方差 。
The probability analysis method of the bearing capacity of composite pile foundation is investigated, which can push the developing of the reliability method of composite pile foundation. Using formula Pu=I (nPp+Ps) calculated the bearing capacity of composite pile foundation, and the model uncertainty factor is also investigated through practical case. The mean and variance of the bearing capacity of the pile and soil are determined after analysis, and so the probability characteristic of the composite foundation is deduced.
