| 摘 要： | 岩体渗透率与应力关系是进行岩体渗流应力耦合分析的基础。基于龙滩水电站边坡岩体渗流压水试验结果和边坡岩体岩性及物理力学性质，对岩体渗透系数和地应力进行了分析计算，给出了边坡岩体渗透率随应力变化的关系式，为进行边坡岩体渗流一应力耦合分析提供了可靠数据。

| Abstract: | Relationship between permeability and stress is the key foundation for coupled seepage-stress analysis of rock mass. Based on the seepage pressure well test and rock mass physical and mechanical properties, the permeability and stress in rock slope of Longtan hydroelectric station are achieved. By analyzing the data, the relation between permeability coefficient and geo-stress is presented, and a key material for fluid-solid coupling analysis is provided, |
