摘要
黄河黑山峡大柳树松动岩体中含有大量的软弱层带 ,这些软弱层带在很大程度上控制了松动岩体的物理、力学性质 ,而且软弱层带在未来的高水位情况下可能发生的渗透变形与破坏更是直接威胁大坝的安全和正常的使用。详细分析了大柳树坝址区软弱层带发生渗透变形的条件 ,明确提出了管涌是发生渗透变形与破坏的主要形式 ,以引起有关方面的重视。
The dynam relaxed rockmass at Daliushu in Heishanxia Gorge on the Yellow River contains a great quantity of weak intercalations, which control the dynam relaxed rockmass' physical and mechanical properties to a great extent. Moreover, in the high water level condition in the future, the possible seepage deformation and failure will directly threaten dam's safety and its normal operation. The authors analyze in detail the seepage deformation conditions of weak intercalations in dam site at Daliushu, and definitely put forward that piping is the main form of seepage deformation and failure in order to draw the related organizations' attention.
