对兴业县瑶冲水库除险加固放水及泄洪建筑物的设计方案比选进行分析,说明小型水库除险加固面临的实际问题,如没有溢洪道,放水设施采用顶管施工困难,征地困难,投资有控制,工期紧。通过变更原审批设计方案,解决了上述问题,并保证了施工进度、质量和大坝安全运行,为类似的小型水库工程设计方案变更提供参考。
This paper analyzes the comparison and selection of design schemes of reinforcement, drainage and spillway construction of Yao Chong Reservoir in Xingye County to illustrate the practical problems faced by small reservoirs in reinforcement and reinforcement. For example, it is difficult to use jacking pipe for spillway and water discharge facilities, Control, tight schedule.
