摘要
把裂隙岩体概化为等效连续介质，建立了统一的渗流－弹塑性应力全耦合控制方程。坝区耦合分析表明耦合和不耦合分析所得的坝区渗流场有一定差别，耦合分析的厂房地下洞室顶部的水压力值增大，且洞室壁面的出渗量也增大。考虑耦合作用的地下洞室群区域的渗控优化布置仍需进一步的研究。
This present paper conceptualized the jointed rockmass as an equivalent continuous medium, thus establishing a set of unified equations for the complete coupling control of seepage-elastoplastic stress. The coupled analysis of dam site shows that the seepage field of coupled analysis is different from that of uncoupled analysis. The water pressure in the roof of underground opening of coupled analysis is larger than that of uncoupled analysis, so is the calculated discharge of the side wall. The further research of region fo underground opening is needed.
