摘要
南江水库大坝坝型为细骨料混凝土砌石重力坝,通过对该工程坝基渗流分析,提出此类坝型的坝基扬压力分布状况和特点.根据原型观测资料采用一元回归分析表明,南江水库大坝坝基帷幕和排水设施布置合理,坝基防渗系统整体状况良好,工作性态基本正常,坝基的渗流状态已趋于稳定,坝基杨压力分布基本满足安全要求.为确定大坝结构稳定和渗流稳定性的安全类别提供了依据.
Nanjiang Reservoir is a gravity dam made up of fine aggregate concrete. The seepage in dam foundation and the characteristics of the uplift location are analyzed. The conclusions show that the curtain and drainage system in dam foundation is in good condition and the seepage is in steady state.
