摘要
根据复合桩基的理论分析和试验结果,结合有限元的模拟分析,提出了一种计算复合桩基沉降计算的新方法——修正简化应力调整法,并对3个工程实例进行了计算。该方法考虑了桩间土的压缩,符合复合桩基的变形特征,计算结果和实测数据的对比分析表明该方法计算简单,概念清楚,具有一定的计算精度,便于在工程中的应用。
On the base of the theoretical analysis,experiment results and numerical simulations,a new method for calculating the settlement of composite pile foundation, modified simplified stress method, is put forwarded,which is applied to analyze three cases.According to the deformation characteristic of composite pile foundation,this method takes the compression of soil between piles into account.The comparison between calculated results and measured data shows that the new method enjoys merits of simplified calculation,clear physical concept and certain precision.It is suggested that the simplified method is convenient to analyze the practical cases.
