【Abstract】 A reliability analysis system for grouting in rock mass is established. The success tree is drawed. On the basis of summing up the grouting theory,limiting condition equation for basic incident of grouting is made up. The logical relation model about first and repeat grouting is made up. The reliability discrimination rule of working status of grouting system is forwarded. A reliability calculation has been made for grouting to stop water in site.The calculation result is discussed.更多还原
