摘要
根据调查成果资料,结合室内分析,总结归纳出秭归县幅典型滑坡、崩塌主要成灾模式。典型滑坡成灾模式主要包括滑移型、冲刷型、崩滑型、碎屑流型等四种类型,典型崩塌成灾模式主要包括软弱基座型、风化卸荷型等两种类型。通过对区内典型滑坡、崩塌成灾模式及其发生发展条件、演进模式的研究,为区内地质灾害防治、风险管控及工程建设提供基础地质依据。
Based on the investigation results and indoor analysis,the main disaster-causing modes of typical landslides and landslides in Zigui County are summarized.The disaster-causing modes of typical landslides mainly include four types:sliding type,scouring type,landsliding type and debris flow type.The disaster-causing modes of typical landslides mainly include two types:weak foundation type and weathering unloading type.Through the study of typical landslides and collapses in the area,their occurrence and development conditions and evolution mode,it provides basic geological basis for geological hazard prevention,risk control and engineering construction in the area,and has important practical significance.
