| 摘 要： | 四川5．12汶川地震震级高，强度大，造成人民生命财产的损失巨大。地震次生灾害特别严重，频繁发生，以坡面地质灾害如崩塌、滑坡、泥石流和地面地质灾害如地裂缝、地面塌陷、道路滑塌以及堰塞湖和社会灾祸最为常见。这些次生灾害以活动断裂为地质构造基础；地表大量松散固体物质为物质来源；强烈频繁的余震、坡面流水和沟谷洪流为动力条件，暴雨、洪水、持续的高温为诱发和触发因素。暴雨、洪水、高温是次生灾害主要的致灾因子，由此形成了三个系列的灾害链，造成人员伤亡和生态环境恶化，影响更加深远。对汶川地震次生灾害的防治要加强监测与动态分析，及时排除堰塞湖险情，严防传染病的蔓延。当前防治应以工程措施为主，植树种草，进行生态修复是进行远期治理的根本措施。

| Abstract: | The secondary disasters take place frequently and damage seriously in Wenchuan quake-hit area,West China.Their causes,hazards and reduction are analyzed and discussed in detail according to field investigations and statistical data.Active faults are their structure foundation;the loose solid surface provides them with material conditions;rich precipitation and earthquakes are their power source.Three main hazard chains are resulted from earthquake,torrential rain and high temperature.They bring up human dea... |
