NUMERICAL MODELING OF GROUTING IN GEOENGINEERING
灌浆的数值仿真分析模型探讨

With the consideration of strengthening mechanism of grouting to geomaterials,the proper grouting modeling methods are proposed. The proposed methods can model the deformation properties of grouted geomaterials by variation of sound wave velocities before and after grouting,and the strength properties by properly estimating the strength parameters of rock joints or soft soils. The damage tensors and seepage parameters of grouted jointed rock mass can be obtained by the representative element volume of grouted materials.
