摘要
天生桥一级电站混凝土面板堆石坝的填筑坝体位移监测通过水管式沉降仪和水平位移计进行 .坝体内安装了 50支水管式沉降仪 (瑞典盒式 )、31支水平位移计 (铟钢丝型伸缩仪 )和 2 8支总压力计 .监测结果表明 ,施工期末 (1999年 3月 )最大坝体沉降是 2 .94 m,相当于坝体高度的 1.7% ,施工期末堆石坝变形模量 Erc平均 4 5MPa,为最大坝体变形 ,促使上游边坡出现裂缝以及面板浇筑前上游边坡明显沉降 .
For TSQ ⅠCFRD the embankment displacements are being monitored by hydrostatic settlement cells and horizontal displacement meters.Settlements and horizontal displacements measured during the construction period and partial reservoir filling are presented.Deformation of the dam body has caused cracks in the upstream slope,a gap between the face slab and the cushion zone slope and significant upstream slope ,a gap between the face slab and the cushion zone slope and significant upstream slope settlements before pouring the face slab.These interesting construction features and related remedial treatments are described and analyzed in relation to the dam performance.
