| Abstract: | Grouting is a rock-stratum strengthening method that fill up the voids and fractures with cement or other materials. Based on the osmotic grouting theory and fractal theory, the paper discusses the factors such as grouting pressure and grouting flowrate in the collapsed zone of soft rock tunnel and also the statistic and calculation method for the porosity rate of collapsed rock mass. The engineering cases show that grouting is an effective way to get across the collapsed zone. |
