北京突发地质灾害防控对策

Prevention and Controlling Idea on Emergent Geological Disasters of Beijing

北京是突发地质灾害较为发育的首都城市之一,地质灾害给人民生命财产带来一定的损失。本文分析了北京市地质灾害分布规律,系统总结了北京地区分布面广、危害性大的泥石流、崩塌、滑坡等突发地质灾害的基本特征。总体上看,北京地区地质灾害隐患类型全,规模小,险情差异大。2003年以来,突发地质灾害次数有较大增加,主要类型为崩塌和地面塌陷。在此基础上,提出北京市突发地质灾害防治思路,即北京地区防治应以调查为基础,监测预警为先导,以搬迁避让为主,工程防治为辅,并从调查评价、监测预警、工程治理等方面,提出了北京地质灾害的防治建议,为地质灾害防治规划提供了参考。

Beijing is one of the capital cities with frequent geological disasters, which brought some loss for people’s lives and properties. Based on the distribution analysis of geological disaster, the development features of debris fow, collapse, landside, surface subsidence due to mining, ground subsidence as well as ground fssure are systematic generalized, furthermore, the prevention and controlling zoning of geological disaster such as survey and evaluation, monitoring and prediction, engineering construction are established, which can ofer some references for geological disaster prevention plan.
