| Abstract: | The engineering mechanical properties of saturated, water-bearing sandy ground, instability failure mechanism and stability control of tunnel surrounding rock are key issues in water-bearing sandy ground tunnel design and construction. Based on the review of research on sand strain localization, the water-bearing sandy ground tunnel surrounding rock stability research is described emphatically. Some issues in progressive failure of water-bearing sandy ground tunnel surrounding rock are presented, which need to be further studied. These works will be helpful to improve the level of bearing-water sandy ground tunnel design and construction. |
| Keywords: | water-bearing sandy ground tunnel surrounding rock strain localization failure mechanism |
