突涌水问题是影响地下工程进行的重要地质灾害之一。针对上述问题,建立了试验平台,以裂隙水、岩石、注浆液三相界面为研究对象,进行了水泥-水玻璃止水浆液在模拟涌水裂隙中的封堵试验。实验表明,增加浆液配合比不利于浆液扩散,但浆液的驱替效果较好,其堵水效果较好。其试验结果规律对地下堵水工程存在一定的指导意义。 Water inrush problem is one of the important geological disasters that affect underground engineering. In view of the above problems, a test platform was set up and the three-phase interface of fissure water, rock and grouting fluid was taken as the research object. The plugging test of cement-water glass slurry in simulating gushing fissures was carried out. Experiments show that increasing the slurry mix is ​​not conducive to the slurry diffusion, but the displacement effect of the slurry is better, and its water blocking effect is better. The results of the test results of underground plugging water there is a certain guiding significance.
