Abstract:Due to its special material composition, formation environment and special structure, red soil usually exhibits engineering characteristics and dynamic characteristics different from ordinary soil. By summarizing the previous research results, the engineering characteristics, dynamic characteristics and seismic response characteristics of red soil in Liuzhou area are studied by numerical simulation methods. The results show that: (1) Except for the liquidity index, the coefficient of variation of each physical property index is small and relatively stable, and the coefficient of variation of each mechanical property is large and relatively discrete; (2) The physical and mechanical properties of red soil in Liuzhou area There is a correlation between the natural water content, void ratio, and density. (3) Through statistical analysis, this chapter gives the relationship between the shear wave velocity and the buried depth of the red soil in the Liuzhou area. The recommended fitting model of the related system has a verified error of less than 5%; (4) The difference between the different kinetic parameters and the measured value is analyzed through the SOILQUAKE program, and the recommended value is given. This work is of certain value to workers engaged in red soil research.
