金沙江点荷载实验数据（2020）

课题获取了青藏高原金沙江流域典型重大滑坡（扎农滑坡、宗绒村滑坡、下归洼滑坡）的基岩物理力学指标。基岩的物理力学指标主要通过点荷载试验得到，获取的物理力学指标为后续的物理模型试验、揭示内外动力耦合作用机制等提供了科学依据。典型滑坡岩块的强度实验采用点荷载仪，每组试件不少于15件，共计5组。点荷载试验的岩石样共有五种，分别为灰岩、蛇绿岩、云母片麻岩、闪长岩和片岩，其中闪长岩为圆柱状径向加载，其余均为不规则岩样，实验结果进行了尺寸修正，实验状态为天然含水量状态。This study collected physico-mechanical properties of bedrock from three typical major landslides (Zhanong Landslide, Zongrongcun Landslide, Xiaguiwa Landslide) in the Jinsha River Basin, Qinghai-Tibet Plateau. The physico-mechanical properties of the bedrock were primarily obtained through point load tests, and the acquired data provide a scientific basis for subsequent physical model tests and the elucidation of the coupling mechanism between internal and external dynamic actions. For strength tests of rock blocks from these typical landslides, point load testers were employed. Each test group contained no less than 15 specimens, with a total of 5 test groups. Five types of rock samples were utilized for the point load tests, namely limestone, ophiolite, mica gneiss, diorite and schist. Among them, the diorite specimens were tested under cylindrical radial loading, while the remaining specimens were irregular rock samples. The test results were corrected for size effects, and all experiments were conducted under natural moisture content conditions.
