FEATURES OF TECTONIC DENUDATION GRAVITY ACCUMULATION IN PLATE SUTURE ZONE OF HENGDUAN MOUNTAIN REGION

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.
