The results show that the strata structure of dip pillar area and the asymmetric I-shaped spatial strata structure formed by excavation are primary causes of abnormalstress concentration.
The secondary parts such as radial sluice gate and its stand were neglected, the number of elements were decreased and the abnormalstress caused by improper loading were avoided in this method.
有限元模型减去了弧形闸门、闸门支架等非主要部件,使模型规模减小,避免了因荷载不恰当引起的应力异常。
