液体-结构-桩基-土体系相互作用动力分析

DYNAMIC ANALYSIS OF LIQUID-STRUCTURE-PILE-SOIL INTERACTION SYSTEM

将工程中常用的密集桩基体系模拟为正交各向异性弹性体,采用样条函数表征桩基和土的位移,不但满足圆柱体柱坐标的极点条件,且待定系数少、边界条件容易处理,用自编专用程序SXJG在微机上对支承在桩基上的储液罐这一液体-结构-桩基-土体系进行了动力分析,得到了一些规律性的结果。

In this paper, the soil-pile system is simulated as an anisotropic elastic solid. The displacement of the soil-pile system is approached by spline function so that the origin condition and the boundary condition can be satisfied. According to the above-mentioned theory and procedure, a special computer program SXJG is compiled to analyze the dynamic behaviour of liquid-structure-pile-soil system. Some regularities of these systems have been obtained.
