白莲河抽水蓄能电站面板堆石坝监测设计与监测资料分析

主要从面板堆石坝坝体内部变形、坝体表面变形、面板钢筋应力、面板混凝土应力应变、面板垂直缝及周边缝接缝变形、坝基渗透压力、绕坝渗流、渗漏量等方面介绍了湖北白莲河抽水蓄能电站上水库面板堆石坝的安全监测设计及安全监测成果。监测资料分析结果表明,目前面板堆石坝沉降和水平位移已趋于稳定,面板应力与变形较小,总渗漏量较小,大坝处于安全工作状态。

Monitoring design and data analysis of concrete faced rockfill dam of Bailianhe pumped storage station

Safety monitoring design was carried out in the concrete faced rockfill dam of Bailianhe pumped storage power station in Hubei Province. The monitoring items included inner and surface defor-mation of the dam body, reinforcement stresses and concrete stress-strain of the panel, deformation of vertical joints and peripheral joints of the panel, seepage pressure at foundation, bypass seepage, the leakage volume and etc. The results showed that the settlement and horizontal displacement of the dam was gradually becoming stable, the stresses and deformation of the panel was small, the total leakage was little and the dam was safe.
