桂东南地区厚层风化壳成因分析及对公路建设的影响

Cause Analysis of Thick Weathering Crust in Southeast Guangxi and Its Influence on Highway Construction

桂东南地区公路沿线地层岩性普遍发育厚层风化壳,残积层及全强风化层厚度大。通过总结区域地质条件及厚层风化壳工程地质特性,分析厚层风化壳形成原因,评价其对公路工程建设的影响,并提出科学、可行的工程措施建议。

Along the highway in southeast Guangxi,thick weathering crust is generally developed,and the thickness of elutrium and full-strength weathering layer is large.By summarizing regional geological conditions and engineering geological characteristics of thick weathering crust,this paper analyzes the formation reasons of thick weathering crust,evaluates its influence on highway engineering construction,and puts forward scientific and feasible engineering measures.
