天生桥一级混凝土面板堆石坝的面板挠度变形采用电平器进行监测 ,安装了 6 4支电平器 ,部分已正常运行了两年多 ,正确记录了施工期间和水库蓄水期间的面板位移 .施工期和水库蓄水期分别从沉降仪和电平器记录的位移值电算出的压缩模量为 Erc=75MPa,Erf=195MPa.蓄水模量与施工模量之比 Erf/ Erc=2 .6 .该值与其它混凝土面板堆石坝观察情况相符合 .实践表明 ,电平器是一个简单、可靠的面板位移监测系统 .
Tianshengqiao a concrete faced rockfill dam deflection deformation monitoring using level device, the installation of 6 4 level, part of the normal operation of more than two years, correctly recorded during the construction and the reservoir during the panel displacement The compressive modulus calculated from the displacement values recorded by the settlement meter and the level meter respectively during the construction period and the reservoir water storage period is Erc = 75 MPa and Erf = 195 MPa. The ratio of water storage modulus to construction modulus Erf / Erc = 2 .6 This value is consistent with the observation of other concrete face rockfill dams. Practice shows that the level meter is a simple and reliable panel displacement monitoring system.
