| 摘 要： | 汶川和芦山地震后四川地震次生灾害频繁发生,以崩塌、滑坡、泥石流和堰塞湖最为常见,主要分布在川西高原、川西南山地的深切河谷地区以及四川地区周围山地.这些次生灾害以活动断裂为地质构造基础,以地表大量松散固体为物质来源,以强烈频繁的余震、坡面流水和暴雨洪水为动力条件,由此形成巨大的灾害链,造成大量人员伤亡和经济损失,其严重后果甚至极大地影响了抗震救灾工作的顺利开展.对于四川地震次生灾害的防治要加强监控,建立预警机制,开展风险评估,因害设防,分层防御.

| Abstract: | Sichuan is vulnerable to the secondary geological disasters, which take place frequently and damage seriously along earthquake zones and rivers at both banks of hillside. The secondary geological disasters bring up human casualty, property losses, environment destroy, and construction engineering damage. In this paper, we summarized the major types of the secondary geological hazards and their characteristics, and discussed the countermeasures we should pay more attention in our future work. |
