摘　　要：根据驮英水库施工导流方式及水文条件,结合枢纽大坝实际施工面貌,分析工程存在的重大险情,并拟定6个围堰破堰方案,采用数值法分析计算各破堰方案对下游的影响,为科学合理制定库区及坝址下游防汛抢险应急预案提供技术依据。According to the construction diversion design and hydrological conditions of Tuoying Reservoir,com⁃bined with the construction progress of main dam,analysis was made on the major danger of the project;six weir breaking schemes were drafted for main dam construction.Numerical method was adopted to analyze and calculate the impact of various weir breaking schemes on downstream area,so as to provide technical basis for the flood con⁃trol emergency plan of reservoir area and downstream area.
