Abstract

The dam in Mianjiang reservoir is located in Jiangyou City, Sichuan Province. It is an irrigation, flood control, small fish and other integrated functions (2) reservoir. It has been built for many years, so there are many problems such as seepage dam, spillway erosion serious, drainage facilities aging. Focus on these issues, this design mainly to reservoir reinforcement, the main contents include the design flood review, peak discharge, recheck computation of spillway maximum discharge capacity, the analysis of dam seepage, the analysis of dam stability, the design of reinforcement and spillway strengthening, all of this based on the Mianjiang reservoir basis of basic data. In order to protect downstream residents, we have to do analysis of dam seepage, and complete the dam heightening project.

Key word : Dam; seepage; flood; spillway; reinforcement
