江西永新斗上水库大坝工程地质问题分析评价

斗上水库位于江西省永新县城西北侧,是集灌溉、防洪、发电等功能于一体的中型水库.水库坝址区出露岩性为石英砂岩,工程区地质环境条件较为复杂.水库自20世纪70年代建成以来,一直处于带病运营状态,水库大坝渗漏、坝基肩稳定性等工程地质问题突出.该文以斗上水库为例,分析了其存在的工程地质问题,阐述了大坝工程地质条件对工程质量的影响,及对水库大坝后期运行管理的影响,对水库除险加固具有重要的指导意义.

Engineering Geological Problem Analysis and Evaluation of Doushang Reservoir Dam in Yongxin Jiangxi Province

Doushang reservoir located in northwest of Yongxin County, is a concentration of irrigation, flood control, power generation, andother functions in a bodyg medium reservoir. Outcrop is quartz sandstone in reservoir dam site area, the complexity of geological environmentalconditions is moderate. Since the 1970s, the reservoir has been in operation state, the geological problems are obviously, such as leakage ofthe dam and dam abutment stability. With Doushang reservoir as an example, the existing geological problems were analyzed, effects of geo-logical conditions on project quality and the reservoir management were analyzed, which has important guidance on reservoir reinforcement.
