| 摘 要： | 汶川8.0级特大地震诱发了以唐家山堰塞湖为典型的大量堰塞湖,对上下游人民生命财产安全造成了严重的威胁和危害。对震后堰塞湖的处置成为今后次生山地灾害减灾的一大关键性课题。在回顾和总结唐家山堰塞湖的应急排险经验的基础上,对泄流槽纵、横断面的优化进行了初步的探讨。同时在开挖过程中,也应考虑堰塞体组成物质、抗冲稳定性、施工设备等因素选择泄流槽体型。震后5～10年是泥石流、滑坡灾害的活跃期,发生大规模泥石流、滑坡堵江事件的可能性也随之增加,期望研究能够为堰塞湖的排险处理提供一定的技术参考。

| Abstract: | A large number of dammed lakes,including the Tangjiashan dammed lake as a typical one,were induced by Wenchuan earthquake,which have brought severe threat and damage to life and property of people around the upstream and downstream.The treatment of dammed lakes after earthquake is a major issue in research on prevention of secondary mountain hazards in the future.Based on review and summary of the experience on emergency treatment of the Tangjiashan dammed lake,optimization for longitudinal and cross sectio... |
