裂隙基岩非稳定渗流场与应力场耦合分析研究

Analysis and Study on Un-stable Seepage Field and Stress Field Coupling of Fissuring Base-rock

现当今面板堆石坝已为筑坝的主流坝型之一,其安全稳定性一直是坝体控制设计的重点,合理的分析渗流场与应力场分布规律对正确评价坝体的安全稳定性具有重要意义。文章在多孔连续介质渗流与应力耦合理论基础上,视地基为连续介质,分析研究连续介质两场相互作用的机理,并开发出适用于连续介质渗流场与应力场耦合的三维数值仿真计算程序,结合工程实例,所得出的结论对类似工程设计具有一定的指导意义。

Slab rock-fill dam has become one of the dominant dam type today,its safe stability has been the key of dam body control design,reasonable analysis for the distribution law of seepage field and stress field is significant meaningful to evaluate correctly the safe stability of dam body. Based on multi-holes continuous medium seepage and stress coupling theory,the foundation was regarded as continuous medium in this paper,the interactive mechanism of two continuous medium fields was analyzed and researched and the tree-dimensional valuable calculation program suitable to coupling of medium seepage field and stress field,combined with project cases,the conclusion was meaningful for similar project design.
