复合桩基沉降计算的可靠度研究

Research on Reliability of the Composite Pile Foundation Settlement Calculation

从复合桩基的沉降计算方法出发,提出了按压缩区域分解法计算复合桩基的可靠度计算模型,并在此基础上提出了沉降可靠度的简化计算方法。结合一个工程实例对比分析了简化计算法的实用性,并在此基础上分析了土模量变异系数对沉降可靠性的影响。

Based on the calculation method of composite pile foundation settlement, an reliability calculation model, is introduced to calculate the reliability of the composite pile foundation according to the stress adjusting method, on the basis of which a simplified method is proposed for calculating its reliability of the settlement. With reference to an engineering project, the practicability of the simplified method is analyzed, in turn, we analyzed the influence on the reliability of settlement by coefficient of variation of soil modulus.
