摘要
通过地电测试方法进行了三维地质结构中浆液扩散行为和过程的监测,结果表明:电极自然电位对浆液扩散具有很强的敏感性;在双扩散层中心注浆试验初期,浆液扩散水平距离和扩散时间的平方根近似成正比关系。因此,可利用地电测试方法对浆液扩散范围和过程进行有效的三维可视化监测和分析,为评估注浆效果(阻水、加固等)提供强有力依据。
The diffusion behavior and process of grout in 3D geologic structure of porous rocks is tested by geoelectric test method. The result shows that （ 1 ） the natural potential of electrode is sensitive to the behavior of grout diffusion; （2） the horizontal diffusion radius of grout increases approximately the square root with diffusion time in the initial stage of grouting test at the center of double diffusion layers. Thus, the geoelectric test method can be used in visible 3 D monitoring and analyzing of the area and process of grout diffusion, which can strongly support for assessment of grouting effect such as water resistance and reinforcement, etc.
