Abstract: Through the comprehensive analysis of the physical indexes and the mechanical indexes used in the soil test results of all kinds of soils in Beijing area,some relationship diagrams are drawn between the indexes of physical property and the indexes of mechanical property based on the data statistics,regression analysis and empirical correction.Then,some regular cognitions and conclusion are summarized.Taking advantage of the regulations and conclusions,we can make correct analysis and judgment to some abnormal phenomena in the soil tests,offered the more rational and more accurate test data for the geotechnical engineering survey and design,in order to assure the quality and safety of the engineering construction.
