摘要
通过对小型水库大坝的渗流和稳定进行计算,得出坝体存在渗透破坏和下游坝坡不稳定隐患,需进行加固处理。根据大坝基础地质、坝体填筑材料以及施工质量等条件,选择3种大坝防渗加固方案并进行优选,同时对大坝坝体进行综合整治;经对加固后的坝体稳定进行校核,结果表明大坝除险加固后安全可靠。
Through calculating the vadose and stability of small reservoir dams, the author finds that seepage hazards exists in dam bodies and instability hazards in lower dam slopes, so they need to be reinforced. Based on dam basic geology, dam filling material and construction quality, the author optimizes 3 kinds of schemes to reinforce the dam. After checking the dam instability, the author finds that the dam is safe and dependable.
