| 摘 要： | 研究了粉喷桩复合地基抗剪强度概率分析的方法。采用面积比的公式计算了粉喷桩复合地基的抗剪强度。分析确定了桩间土和桩体抗剪强度的均值和方差，由此得出了复合地基抗剪强度的概率特性。最后用一实例说明计算过程。

| Abstract: | In the paper,the probability analysis method of the cut strength of cement-soil pile composite foundation is investigated.The cut strength of cement-soil pile composite foundation is calculated using the area ratio formula.The mean and variance of the cut strength of the cement pile and the soil between the cement piles are ascertained after analysis,and so the probability charcteristic of the composite foundation is deduced.Finally,an example is used to illustrate the calculating process. |
