Abstract：Oversize deep water holes have occurred in Goupitan and many other hydropower stations. Therefore， it’s of great engineering value for emergency rescue to research on the rapid plug of oversize hole. Based on the characteristic of the large-scale deep water hole，this paper proposes a sequential riprap filling method，which includes reinforced gabion，stone ballast，composite geo-membrane，mold bag concrete and clay woven bag. An analytical calculation method of evaluate the plug effect is proposed. Finally，the riprap filling project is calculated by using analytical calculation method and finite element method. The results show that the seepage discharge can meet the requirements after the completion of plugging. Therefore，the sequential riprap filling plugging method can be applied successfully in plugging large-scale deep hole. The clay woven bag plays an important role in the plugging process. In order to guarantee the plugging effect，more attention should be paid to the quality of the filling of the clay woven bags. Attention should be paid to avoid the occurrence of local vacancies in the clay woven bags，especially for the clay woven bags at the bottom of the slope. A method for determining the optimum thickness of the clay woven bags is proposed.
