چکیده انگلیسی
The karst tunnel water inrush disaster causes not only casualties, but also serious damage to the groundwater system. At present, the grouting technology is mainly to adopted to control water inrush disaster. But the theory of dynamic water grouting is imperfect, and the grouting material is single. By the technical means of combining the theoretical analysis, the indoor test and the engineering projects, this paper deeply researches on the slurry diffusion and plugging mechanism of dynamic water grouting. In this paper, the dynamic water plugging criterion of the glass fiber cement slurry is formulated, and the flow pattern test is carried out for cement slurry and consolidation body with different glass fiber proportions. According to the analysis of experiment conclusion and engineering effect, this paper draws the following conclusions. Firstly, for the slurry mixed with a small amount of glass fiber (≤0.4%), when Power-law fluid changes to Bingham fluid, the water-cement ratio is 0.8 and when Bingham fluid changes to Newtonian fluid, the water-cement ratio is 1.2. In addition, when the water-cement ratio of the pure cement slurry is large, the flow pattern of the slurry is constant. Secondly, when glass fibers are added to the pure cement slurry, the fluidity of the pure cement slurry will be reduced. The larger the ratio of glass fiber is, the greater the influence is. Thirdly, by using glass fiber cement slurry for dynamic water grouting, the condition of water inrush is effectively improved.
