【摘要】 实验室振动台模拟试验是研究地震滑坡的手段之一。本文选取1933年岷江上游叠溪地震诱发各类滑坡中的两种(岩质顺层滑坡和深覆盖层孔隙水压力激增型滑坡)为例,借助水平加垂直双向振动模拟试验台,进行地震滑坡的振动台模拟试验。以此分析和探讨各种斜坡在地震力的作用下的变形破坏的规律和机制,并以此验证前人所建数值模型和计算模型的正确性。斜坡模型的建立是在对叠溪地震进行详细的分区分带研究,对叠溪地震形成演化机制的深入探讨后建立起来的,具有较强的针对性和模拟性。更多还原

【Abstract】 Vibration table simulation test is one of methods to make research on earthquake landslide.Two types of landslide(rock bedding plane landslide and pore water pressure increment landslide under deep covering) which occurred in Minjiang upriver in 1933 are induced by Diexi earthquake,and they are researched by two-way vibration table simulation test.Then deformation failure rule of slope under the seismic force is analyzed,by which the numerical model and computational model built by others is proved correct.After studying on division area and evolutionary pattern of Diexi earthquake in detail,slope models are established,which are of pertinence and simulation property.更多还原
