某水库大坝防渗加固措施及稳定复核

Anti-seepage Reinforcement Measures and Stability Review of a Certain Reservoir Dam

某水库建成于1978年,建库45年来经济效益显著,对下游防洪和地区国民经济发展发挥了重大作用。但水库在过去多年的运行中,出现大坝坝体渗漏、上游坝坡冲刷淘蚀严重,输、泄水建筑物不能正常运行等问题。文章针对大坝坝体渗漏、坝坡防护加固措施等设计方案进行了详细的阐述,并对大坝防渗加固后坝体渗流稳定进行了复核。通过对大坝坝体、坝坡防渗加固处理,排除了水库存在的安全隐患,确保了水库大坝的安全运行,让其充分发挥水库的综合效益。

A certain reservoir was built in 1978,with significant economic benefits over the past 45 years.It has played a significant role in downstream flood control and regional national economic development.However,in the past years of operation,the reservoir has encountered problems such as dam leakage,severe erosion of upstream dam slopes,and inability to operate water transmission and discharge structures normally.The article provides a detailed explanation of the design schemes for dam leakage and slope protection and reinforcement,and conducts a review of the dam seepage stability after the dam anti-seepage reinforcement.By strengthening the anti-seepage measures of the dam body and slope,the safety hazards of the reservoir have been eliminated,ensuring the safe operation of the reservoir dam and fully leveraging the comprehensive benefits of the reservoir.
