摘要
在岩土工程中,就灌浆这一施工措施对岩土体力学特性的影响进行了较全面的分析讨论,并在此基础上提出了灌浆对岩土体变形、强度、损伤及渗透等力学量的量化影响模型与分析计算方法。为进一步在岩土工程数值仿真分析中考虑灌浆的力学效果提供了科学依据。
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 parameter of grouted jointed rock mass can be obtained by the representative element volume of grouted materials.
