张峰水库大坝心墙与下游反滤过渡层内部位移分析

Internal Displacement Analysis of the Dam Core Wall and the Downstream Reversed Filter and Transition Layer

通过对0+250和0+440两个剖面埋设的位移计式沉降仪的测值进行甄别及修正,再选取不同水位下的5个时间节点来对心墙、下游反滤层过渡层沉降形态进行分析,最终反映坝体心墙、下游反滤层过渡层的沉降情况。

Measured values obtained from displacement settlement meters that were buried in 0＋250 section and 0＋440 section were identified and corrected. Five time nodes under different water levels were selected to analyze the sedimentation forms of the core wall and the downstream reversed filter and transition layer. The results could reflect the sedimentation situation of the dam core wall and the downstream reversed filter and transition layer.
