| 摘 要： | 采用积分方程法推导出求解桩-桩、桩-土、土-土之间的相互作用系数所需要的第2类Fredholm积分方程，利用叠加原理对复合地基进行计算分析。通过与试验结果的比较，验证了计算方法的正确性，并对复合地基的沉降、各桩以及土之间的荷载分担情况进行了参数分析。该方法能够用来分析大规模复合地基，具有一定的工程应用前景。

| Abstract: | By the method of integral equation,the second kind Fredholm's integral equation is deduced to solve the interaction factors of pile-pile,pile-soil and soil-soil.Using the principle of superposition,the composite foundation is calculated.The validity of the present method has been verified through comparing with the experimental result.A parametric analysis is made to study the composite foundation settlement and the loads sharing by the individual pile and subsoil.The proposed method could be used to analyz... |
