摘要/Abstract

摘要： 基于对重庆库区工程弃渣泥石流发育的宏观地质环境较系统地分析,认为重庆库区工程弃渣具备发生泥石流灾害的可能性;选取沟床比降、沟床糙度、汇水面积、洪峰流量等10个因子分析了重庆库区工程弃渣泥石流的稳定性条件,建立了适合重庆库区工程弃渣泥石流的起动机理;并以重庆库区奉节县城李家大沟工程弃渣为实例进行验证,说明工程弃渣的活动性是可以通过实际验算来具体确定的,为泥石流的有效防治提供科学依据。

Abstract: From systematic ana lysis of the geological environment in which Chongqing reservoir construction spoil debris flow developed, it was found that it was probable to occur large and extra large debr is flow disaster in Chongqing reservoir; from the analysis of 10 factors such as groove gradient, groove roughness, water catchment area and flood peak, the stability condition of Chongqing reservoir constrction spoil debris flow and form initiation mechanism of the debris flow was discovered; the construction spoil of Lijia Valley, Fengjie county, Chongqing reservoir was taken to demonstrate that construction spoil activity could be determined by actual checking, which could provide scientific basis for effective prevention and control of debris flow.

Key words: debris flow, construction spoil, mechanism, Chongqing reservoir
