摘要
区域山体稳定性是刘国昌先生于20世纪60年代提出区域工程地质学的内容之一,区域山体稳定性的问题受两个区域性要素的控制,即区域稳定性工程地质的区域性与地带性要素。本文以横断山区板块缝合带构造剥蚀重力型堆积特征为主要研究对象,说明区域稳定性工程地质区域性要素与横断山区铅直地带性要素对区域山体稳定性的影响。并且进一步论述了河床深厚覆盖层具有全球性特征,及其与冰期海平面下降以及区域地壳隆升两者之间的关系。
Regional mountain stability is one of the contents of regional engineering geology proposed by Prof.Liu Guochang in the 1960 s.The problem of regional mountain stability is controlled by two regional factors,namely regional and zonality elements of regional stability engineering geology.This paper takes the characteristics of tectonic denudation gravity accumulation in plate suture zone of Hengduan Mountain area as the main research object and illustrates the influence of regional factors of regional stability engineering geology and vertical zonality factors in Hengduan Mountain area on regional mountain stability.The paper further discusses the global characteristics of deep overburden on the river bed and its relationship with sea level decline and regional crust uplift during ice age.
