Abstract: Using statistical regression analysis, mechanical parameters and bearing capacity of the regional silty clay were studied based on engineering geology and bearing capacity data from 28 sites in Shenyang. Based on the unified strength theory to improve Terzaghi theory, the empirical formula of bearing capacity of shallow foundation in Shenyang area is established. The research show that: within the study area of shallow silty clay, the variation of the physical parameters is small, the correlation of the physical parameters is conspicuous, the variation of the mechanical parameters is large, and the cor-relation of the mechanical parameters is not conspicuous. There is a linear relationship among the standard penetration test values,lateral pressure test values,and soil test parameters values with the bearing capacity of the shallow silty clay, plastic index and static side pressure coefficient. The regional empirical formulas of bearing capacity and the bearing capacity formula of Shenyang area of shallow foundation to establish improved Terzaghi theory, and the actual bearing capacity have higher uniformity. The research results can provide necessary references for the reliable design of regional foundation and determination of bearing capacity.
