摘要
对一个实际基坑支护结构分别按经典的朗肯土压力法和弹性地基梁法计算了支护桩的结构内力。由于弹性地基梁法考虑支护结构与土的变形协调,较好的模拟桩土之间的作用,比采用传统的经典土压力法更加符合实际情况,因此在同等条件下具有更好的经济效益。但按照弹性地基梁法进行基坑设计时,确定支护桩桩长等参数应当依托经典土压力法的计算结果。
A soldier pile's structural internal force was calculated by elastic foundation beam method and Rankine earth-pressure method separately.The elastic foundation beam method,which considers the deformation compatibility of the supporting structure and soil and better simulates the action between the pile and earth,is in more conformity with the actual condition compared with the classic earth pressure method,and thus has a better economic efficiency in the same conditions,but when designing the foundation pit,the soldier pile's parameters,such as length of pile,are determined by the result of classic earth pressure.
