摘　　要：部分均质坝水库因修建年代久远,修建时技术落后、投资不足等问题,在运行多年后存在较多影响水库正常运行的安全问题。对于均质坝水库的安全鉴定往往需要考虑较多因素,因此以上马槽箐水库为例,采用数值现场勘察和数值模拟结合的方式进行安全性鉴定评价,论证结果表明水库坝体抗滑稳定性和防渗水存在问题,需要进行加固处理。溢洪道和输水涵洞情况较好,不会影响水库安全运行。分析成果可以为大坝除险加固具体实施提供有力的技术支撑。Some homogeneous dam reservoirs have many safety issues that affect the normal operation of the reservoir after years of operation due to their outdated construction,outdated technology,and insufficient investment during construction.The safety assessment of homogeneous dam reservoirs often requires consideration of multiple factors.Taking Shangma Chaoqing Reservoir as an example,this paper uses a combination of numerical on-site investigation and numerical simulation to conduct safety assessment.The results indicate that there are problems with the anti-skid stability and water seepage prevention of the reservoir dam body,and reinforcement treatment is needed.The spillway and water conveyance culvert are in good condition and will not affect the safe operation of the reservoir.The analysis results can provide strong technical support for the specific implementation of dam reinforcement.
