摘要
针对马家岩水库龙门沟坝址的Z11、Z12、Z13等组岩层结构面(软弱夹层)进行的原位直剪强度试验3组(15点)和室内直剪(中型直剪)强度试验26组(155点)试验成果,以及4组矿物成份、化学成份等物理性质的试验成果,分析研究并初步揭示了砂岩结构面抗剪强度特性。
The following tests were carried out to study the shear strength characteristic of sandstone fracture in Longmengou dam site of Majiayan reservoir： The first is 3 groups of in-situ direct shear strength test on the fractures of rock Z11, Z12 and Z13 （ 15 points）, the second is 26 groups of laboratory direct shear strength test （ 155 points）, and the third is 4 groups of physical test which include miner identification and chemical composition analysis. Some laws were discovered based on the above work.
