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.
