摘要
丹江口大坝加高工程河床坝段防渗帷幕已运行30余年,局部区域渗流、渗压异常,大坝加高后其运行条件发生变化,能否满足要求,需对其防渗效果进行全面检测,并通过相应的试验研究,对现有帷幕的效果和耐久性作出评价,以确定其补强灌浆部位及方法。
Curtain grouting of the Danjiangkou dam have been running more than thirty years with part of it being of seepage and infiltration pressure unconventionality. After Danjiangkou dam have been heightened, the running condition will change, whether or not to meet the request, the curtain grouting needs all-sided back-check. By carrying out related examination and research to estimate the effect and endurance of the existence curtain we can confirm position and method of the reinforce grouting.
