原位变形试验在阿尔塔什水利枢纽右岸边坡F9断层中的应用

摘要

Two groups of rock mass situ deformation tests are conducted on Altas Hydro -junction Dam Right Bank Slope F 9 Fault to determine the deformation condition of F 9 fault mylonite under different pressures as well as deformation and deformation modulus of the corresponding formation .The change rules of mylonite physical and mechanical properties with pressure are analyzed and studied through test on F 9 fault mylonite, thereby providing key parameters on the high slope stability evaluation of the fault.%　　在阿尔塔什水利枢纽坝址右岸边坡 F9断层上进行了2组岩体原位变形试验，以确定 F9断层糜棱岩在不同压力的作用下变形情况及相应地层的变形模量和弹性模量。通过 F9断层糜棱岩层试验工作，对糜棱岩层物理力学性质随压力的变化规律进行了分析研究，为存在该断层的高边坡稳定性评价提供关键参数。
