桩基承台梁结构分析的新方法

A New Method to Analyse Pile-Cap Structure

以分层地基模型并采用有限元 有限压缩层的计算方法为基础建立起桩土支承体系刚度矩阵 ,从而导出桩 土 承台梁的共同作用方程。通过笔者编制的计算程序分析了考虑桩土共同作用后的承台沉降及桩顶荷载 ,计算结果同弹性理论方法比较一致 。

Based on the finite element finite compressible stratums method, the stiff matrix of the pile soil sustaining system is established and interaction equation is elicited. Some useful conclusions are concluded by applying program analyzing the settlement of pile bearing beam and the loads on the top of piles under the condition of pile soil interaction,the results is approximately in accordance with those analyzed by elastic theory method.
