中文摘要：
地震导致山体变形破裂是一个复杂的演化过程,文中通过一些典型实例的地质分析,总结归纳了高地震烈度区山体变形破裂失稳有一定代表性的倾外层状体斜坡滑坡型、高陡块（层）状体斜坡崩塌型、软弱基座体斜坡滑坡型等3种典型性地质力学模式。自主创新研制、设计、探索了一套振动条件下地质力学模拟试验的设备模型和方法,并对3种典型性地质力学模型进行机制模拟试验。通过变形破裂演化过程模拟再现试验,从中揭示出一些振动条件下变形破裂的典型迹象和重要证据,充分再现了典型地震失稳机制的形成条件、相关性因素以及演化规律,为进一步研究分析提供科学可靠的试验数据和证据。
英文摘要：
The deformation fracture of mountains caused by earthquake is a complicated evolved process. In this paper, three typical geomechanics modes are summarized and concluded, i.e. the outer-inclining bedded landslide model, the high-steep block （layer） bedded slope collapsing model and the weak base landslide model, which are representative for the deformation fracture and instability of mountains in areas with high earthquake intensity. We have also indigenously developed, designed and explored a set of geomechanics modeling test equipment, models and techniques under vibration to conduct the mechanism modeling test of the three typical geomechanics models, concepts and models. Through the modeling reproduction test of the evolved process of deformation fracture, typical phenomena and important evidence of deformation fracture under vibration are shown and formation conditions, relevant factors and evolvement principles of typical earthquake instability mechanism are presented to offer scientific and reliable test data and evidences for further research and analysis.
