摘要
古滑坡由于发生时间久远并且往往规模较大,受到扰动后存在复活的可能性,给工程建设带来极为不利的影响,对其触发因素的分析有助于追溯滑坡发展演化历史,探究其现状。文中以位于青藏高原东南缘某古滑坡为研究对象,结合数值模拟结果及地质环境条件分析,认为该古滑坡由地震触发形成,可结合地震滑坡特点对其采取合理防护措施。
Due to occurred long time and has large scale,the ancient landslide has the possibility of resurrection after disturbance,which brings a great negative influence to the construction,analyzing of the ancient landslide trigger factors can help trace the developing history and explore the current situation.In this paper,an ancient landslide located in the southeastern of Tibetan Plateau is discussed,based on the numerical simulation results and the geological environment conditions,the result shows that the ancient landslide was trigged by ancient earthquake,therefore,it can provide an evidence for the seismic landslide taking reasonable protective measures.
