Abstract: Granite residual soil, mostly sandy sticky clay, is widely distributed in Guangzhou, sharing many universals despite the different characteristics. This paper takes the granite residual soil in eastern Guangzhou as the research object, and obtains a large amount of data through field research, laboratory test and insitu soil test, carrying out the statistical analysis of many physical and mechanical indexes, such as unit weigh, water content, void ratio, plastic limit, liquid limit, plasticity index, liquidity index, coefficient of compressibility, modulus of compressibility, cohesion friction, angle of internal and standard penetration test blow count. Also the paper offers the statistics and the range of physical and mechanical index, analyzes the correction between various indicators, which provides a geological basis for related engineering construction.

Key words: eastern Guangzhou; granite residual soil; physical mechanical index; statistical analysis; correlation analysis
