Study on In-Situ Direct Shear Test of Weak Structural Plane of Rock Mass in Guxian Hydro-Junction Project
软弱结构面对坝基抗滑稳定极为不利，古贤水利枢纽工程坝址区岩体软弱结构面发育，为确定其软弱结构面抗剪强度参数，在坝址区PD204、PD205、PD207、PD302试洞开展了现场软弱结构面抗剪强度试验，根据试验观测数据，计算得到了软弱结构面的抗剪断和抗剪强度参数。从试验结果分析来看，其抗剪断强度略大于抗剪强度。
The weak structural plane of rock mass is harmful to anti-sliding stability of dam foundation. The weak structural plane of rock mass in Guxian Hydro-Junction Project is highly developed. In order to obtain the anti-shear parameters of weak structural plane of rock mass in Guxian Hydro-Junction Project,in-situ direct shear tests were carried out on experimental cavities of PD204,PD205,PD207 and PD302 in the dam-site. The anti-shear parameters of weak structu…查看全部>>
