| 摘 要： | 采用液体溶质水动力弥散方程及其相应分析方法描述治理破裂井筒注浆的浆液运移过程,通过坐标变换推导出径向水流条件下考虑吸附作用的浆液浓度解析公式。同时,结合一个煤矿风井堵水工程实例,介绍了如何根据现场观测资料,采用标准曲线法分析流动浆液吸附性参数和指导注浆进程的应用过程。

| Abstract: | Considering the significance of grout's dispersion in running ground water in the aquifers, a hydrodynamic dispersion model of liquid solute is presented to characterize grout transport in salvation course of ruptured shaft linings, and an analytical solution of grout concentration in radial flow is developed by coordinate conversion. With an instance of a coal mine air-shaft mending engineering, it is demonstrated to form standard curves from in-situ observation data, analyze the dispersivity and absorptivity parameters of flowing grouts and guide the water-block grouting course with the model. |
