地震滑坡危险性评价及编图——以映秀震中区为例

摘要:
提要:虽然宣称地球已进入地震多发期目前学术界还存在不少争议,但不得不承认近期的破坏性强震发生的频率较以往高。强震诱发的滑坡灾害也越来越成为了地质学家们研究的热点。在对一个地区发出中长期地震预报之后,如果也能相应地对该地区的斜坡稳定性进行评价,从而预测地震时滑坡最可能发生的地段,这对于减轻震区人民的伤亡和财产损失将具有重要的意义。本文对目前常用的地震滑坡危险性评价方法进行了简要介绍,并以“5.12”汶川地震映秀震中区为例,运用Newmark方法对该区进行了地震滑坡危险性评价和编图示范,探讨了目前常用地震滑坡危险性评价方法的优缺点及今后区域性地震滑坡危险性评价的发展方向。

Abstract:
Abstract:Although there exists controversy concerning the problem whether the Earth has entered into the earthquake-prone period or not, it is generally accepted that the frequency of the recent devastating earthquake is higher than that in the past. The earthquake-induced landslides are increasingly becoming the research focus of geologists. The prediction of the earthquake-induced landslide prone area and the assessment of the seismic landslide hazards are of great significance for reducing casualties and property losses after a regional long-term earthquake prediction. In this paper, the commonly used seismic landslide hazard evaluation methods are presented and the advantages and disadvantages of these methods are discussed. As an example, the seismic landslide hazards assessment and mapping in Yingxiu area was conducted by using Newmark model.
