摘要
利用回弹仪测取结构面的硬度,估算其单轴抗压强度JCS;利用钢卷尺测算结构面的起伏度,估算其粗糙度JRC;运用Barton提出的结构面抗剪强度公式计算出沐若水电站建坝岩体中缓倾角硬性结构面的抗剪强度值。
The resiliometer was used to measure the hardness of the structural plane,and the joint compressive strength（JCS） was estimated;the steel tape was used to measure the discontinuity waviness,and the joint roughness coefficient（JRC） was estimated;the structure plane shear strength formula which submitted by Barton was used to calculate the shear strength value of the hard structural plane with low to middle dip angle in rock mass at the dam of the Murum hydropower station.
