梧州市花岗岩风化壳工程地质研究及垂直分带

ENGINEERING GEOLOGICAL STUDY ON WEATHERING T CRUST ON GRANITE IN WUZHOU CITY AND ITS VERTICAL ZONING

花岗岩风化壳由表及里有不同的风化等级。认识风化程度的差异，给出各风化层的判别标准，这对于风化壳工程地质性状的研究，评价建筑场地的稳定性极为重要。本文在系统地搜集梧州市花岗岩风化壳的地质资料和已有的土工试验资料的基础上，进行薄片显微照像分析、颗粒分析。结合城市工程地质勘察工作特点，给出了梧州市花岗岩风化壳垂直分带的划分标准。

Because the granite body exposed on the ground surface and the environment change of physical and chemical conditions,the weathering crust on the granite varies in its weathering degree with depth.It is very important for engineering geological study and stability evaluation of constrution site and for analysis of different zones of the weathering crust.The outhor on this paper,basing on systematical collecting the geological data Guilin geotechanical data,thin section analysis and grain size analysis,gives a zoning of the weathering crust on the basis of geologic characters,drill data and dyamic experiment,soil geotechnical and shear experiment on the weathering crust on granite in Wuzhou city.
