摘要
以大量的桩基水平静载荷试验实测资料为基础 ,提出了一种水平土抗力与深度、位移的函数关系以及水平地基反力系数与土质指标的函数关系 ,并利用相似原理 ,将非线性有限元的数值计算转化为简单的查表计算 ,建立了一种新的桩在水平荷载作用下的非线性计算方法—— NL法 ,39根桩的实例计算结果表明 。
Based on a great number of in situ tests, the paper presents the relationship of soil resistance vers depth and lateral displacement, the relationship of lateral foundation reaction factor vers soil indexes. Based on the principle of similitude, we have replaced non linear FEM programming calculation with tabulation method-NL method. Case history of 39 piles has illustrated that the method is of reliable precision and practicability.
