用非线性有限元分析倾斜荷载下的群桩基础

Application of non-linear limited element analysis in the pile group basis under inclination load

采用接触面单元来考虑荷载作用下桩与土体及承台与土体间的滑移、开裂,在应用桩的等效宽度概念将空间问题简化为平面问题后,开发出能考虑桩周土弹塑性及连续性等因素的倾斜荷载下群桩内力及位移分析的计算机程序,最后通过实例分析说明利用非线性有限元对倾斜荷载下群桩进行分析的方法。

It applies interface element in considering slide and crack between pile and soil, cap and soil. After the application of equivalent width of piles simplifying space issue into plane issue, it develops the process that can analyze the interior power of pile group and replacement under inclination load and makes the elastic-plastic property and continuity of the soil around pile into consideration. At the end of this article, it takes an example to analyze the method of applying non-linear limited dement analysis in the pile group basis under inclination load.
