摘要
弹性地基上的筏板基础由于受上部结构和地基的共同影响，在工程设计中很难找到既简单又接近于实际情况的计算方法．建立在文克尔弹性地基假定基础上的有限差分法由于其计算结果和实际情况误差较大，故其在工程设计的应用受到很大的限制。木文应用有限差分法对假设为半无限弹性体地基上的筏板基础的变形和内力进行了计算，并对不规则边界提出了具体的解决办法。
It is difficult to find out the suitable solution to mat foundation based on elastic body in civil structural designing because it is influenced by both upper structure and building foundation. The application of finite difference method solution on the basis of Winker's hypothesis is restricted in engineering for its great error.In this paper,the finite difference method is used to analise the mat foundation based on semi-infinite elastic body,and an improved suggestion about how to deal with the noriregular boundary is given.
