摘要
本文针对弹性地基梁法存在的问题,考虑水闸闸室和地基的共同作用对一单孔水闸进行了二维有限元分析,将底板内力和应力结果与弹性地基梁法所得结果进行比较.分析中考虑了多种因素对底极内力和地基反力的影响,进行了九种情况的有限元计算.成果表明,对于平底板内力和地基反力都与弹性地基梁法所得结果有差异,有限元结果更较为合理.
In view of the existed problems of elastic foundation beam method (EFBM), this paper studies a single-span sluice by using two-dimensioual FEM considerin-g the common furetion of sluice chamber and foundation. The computed results of floor moment and stress are compared with them of EFBM. And taken the effects of some factors on floor moment and foundation stress into account ,the finite ele-ment calculations of nine corditions are given . It is showed that the results offlatfloor moment and fourdation stress are not comform to them of EFBM. The fi-nite element results are more reasonable.
