本文考虑到三峡工程坝基岩体的非均质各向异性特征,采用三维有限单元法计算不同防、排水条件下坝基扬压力大小和分布.考虑到结构面的控水作用,文章还分析了结构面产状要素对坝底扬压力大小的影响.
In this paper, taking into account the heterogeneous anisotropy of the dam foundation of the Three Gorges Project, the three-dimensional finite element method is used to calculate the size and distribution of the uplift pressure of the dam foundation under different conditions of prevention and drainage. Considering the water control action of the structural surface, Influence of Producing Factors on Uplift Pressure at Dam Bottom.
