| Abstract: | Due to the advantages of low cost and easy construction, soil nailing wall is wildly used in slope supporting engineering. Taking the treatment of cracks at high slope of dry dock for immersed tunnel from the Bio island to the University City as the object of study, numerical simulation is used and the genesis of cracks on soil mass analyzed. As a result, load reduction on the slope top and revertment at the slope toe are adopted as the emergency measures for soil nailing wall. It ensured the safety of the high slope. |
