摘要：

The soil layers are of non-uniform distribution and variability in the grouted region, and their parameters obey the distribution laws. Based on the random fractal theory and the characteristics of the related physical parameters, a random distribution model for the physical parameters of non homogeneous soil strata is established. The soil fractal mesh nodes are connected into triangular meshes based on the Delaunay method, using the triangle area coordinates interpolation method to achieve the soil dynamic parameters in the fractal grids to pass to the finite element mesh of grouting. Applying the fluid-solid coupling theory, considering dynamic change of physical parameters of soil and time-varying effect of slurry, the characteristics of dynamic change of the physical parameters are analyzed, and the diffusion scope and concretion shape of the slurry in non homogeneous soil strata are studied. The material parameters of irregular concretion are defined, and the characteristics of stress and deformation under loads after grouting are analyzed. © 2015, Editorial Office of Chinese Journal of Geotechnical Engineering.
