摘要
对强地震多发区黄河黑山峡下游段岩体破坏特征进行了分析,研究表明,地震作用下裂隙的生成与地震波的传播具有同时性、继承性和纵横波在岩体破坏中的拉张和剪切共同作用的双重性等特点。对岩体地震破坏机理及岩体地震破坏模型进行了初步探讨。同时对地震破坏后岩体地球物理特性的变化进行了研究,发现研究区大范围地球物理参数明显变异,说明强震对坚硬的岩体同样具有严重的破坏性。
Based on the analysis of failure characters of the downstream rock mass at Heishan Gorge on Yellow River, the study shows that some characteristics exist between the generation of fracture and the propagation of seismic wave under earthquake action, including simultaneity, inheritance, and the p and s waves＇ dual impacts of tensile and shear fracture on rock mass failure. A preliminary discussion is made on the failure mechanism and the failure model of earthquake for rock mass. And a study is carried out on the variation of geophysical features of rock mass destructed by earthquake, which finds that the geophysical parameters vary significantly in the most studied area and proves that the strong earthquake does the same serious destructiveness to hard rock mass.
