摘要
当前,风岩水库均质土坝存在坝坡未闭合影响水库大坝安危、防浪墙高度不满足防洪要求、坝体渗漏破坏等问题。为恢复水库正常蓄水灌溉功能,结合大坝安全复核成果,设计采用增加防浪墙高度和帷幕灌浆的除险加固方案。经详细计算和论证分析表明:设计的除险加固方案合理可行,工程实施后大坝整体安全稳定。
At present,the homogeneous earth dam of Fengyan reservoir has some problems,such as the dam slope is not closed,the dam safety is affected,the height of the wave wall does not meet the requirements of flood control,the dam leakage damage and so on.In order to restore the normal water storage and irrigation function of the reservoir,combined with the results of dam safety review,the reinforcement scheme of increasing the height of wave wall and curtain grouting is designed.The detailed calculation and demonstration analysis show that the designed reinforcement scheme is reasonable and feasible,and the dam is safe and stable after the implementation of the project.
