摘要

浆液在多孔介质中的扩散路径对渗透扩散范围和注浆效果具有非常重要的影响。采用理论分析，以分形特征与宾汉姆流体在多孔介质中的渗流运动方程为基础，揭示了考虑扩散路径的宾汉姆流体渗透注浆机制，并利用团队前期开展的渗透注浆试验对其进行了验证。分析了多孔介质孔隙率、宾汉姆水泥浆液水灰比、多孔介质渗透系数、注浆压力、地下水压力等对扩散半径的影响变化规律。同时，基于Comsol Multiphysics平台，采用计算机编程技术二次开发得到了考虑扩散路径的宾汉姆流体渗透注浆机制的渗透注浆三维数值模拟程序，并以此开展了宾汉姆水泥浆液在多孔介质中渗透扩散形态效果的数值模拟。研究结果表明：与不考虑扩散路径的宾汉姆流体渗透注浆球形扩散公式获得的扩散半径理论计算值相比，采用考虑扩散路径的宾汉姆流体渗透注浆机制得到的扩散半径理论计算值更接近试验值。该研究成果可为实践注浆工程提供一定的理论支撑。

Abstract

The diffusion path of grout in porous media has a significant effect on the diffusion range and grouting effect. Based on the fractal characteristics and the seepage motion equation of Bingham fluid in porous media

the penetration grouting mechanism of Bingham fluid considering the diffusion path was revealed through theoretical analysis

and verified by the penetration grouting test carried out by the team in the previous studies. The effects of porosity of porous media

water-cement ratio of Bingham cement slurry

permeability coefficient of porous media

grouting pressure and groundwater pressure on diffusion radius are analyzed. In addition

a 3D numerical simulation program of penetration grouting mechanism of Bingham fluid considering the diffusion path was developed through Comsol Multiphysics platform. Then the penetration and diffusion morphology effect of Bingham cement grout in porous media was investigated by the developed simulation program. The results show that the theoretical calculation value of diffusion radius obtained by using the Bingham fluid penetration grouting mechanism considering the diffusion path is closer to the experimental value than that obtained by the spherical diffusion formula of Bingham fluid penetration grouting without considering the diffusion path. The results can provide theoretical support for practical grouting engineering.
