摘要:
在简要介绍了位移模型有限元法计算刚性路面荷载应力的一般概念后,本文对于S.K.Wang与Y.K.Chueng最先提出的半空间地基假定下刚性路面荷载应力有限元分析中所采用的地基反力处理方法提出一些不同的看法。作者认为采用集中反力法不符合荷载移置的静力等效原则,并且地基反力的分块方法也不够妥当。木文提出以均布反力代替集中反力进行应力计算。通过计算结果的对比分析,证明均布反力法更为合理。此外,本文对于面积相等的圆形均布菏载与方形均布荷载的计算结果进行了比较,证明二者是等效的,可以相互置换。
Abstract:
After briefly introducing the general concept of computation of load stresses in rigid pavement by using finite element method in displacement model, this paper presents a method of treatment of foundation reaction, which is different from that used by S. K. Wang and Y. K. Chueng. The author points out that the concentrated reaction assumed by S. K. Wang and Y. K. Chueng is not consistent with the principle of Static equivalency in load transposing, and the division of blocks of foundation reaction is inadequate. In stress computation, the author uses a uniformly distributed reaction instead of concentrated reaction. The result of-computation shows that the uniformly distributed reaction is more reasonable than the concentrated reaction. Besides, the results with circular-shaped and square-shaped uniform loads of the same area have also been compared. It is shown that they are identical.
