宁波溪口抽水蓄能电站厂房部位观测资料分析

Analysis on prototype observation data of Xikou pumped storage power station

溪口抽水蓄能电站厂房部位布置了各种类型的观测设备,具体为引水钢管和蜗壳钢板上的钢板计,蜗壳外围混凝土内的应变计,井壁和基础部位的孔隙水压力计。文中根据观测仪器从埋设至1999年的观测资料,分析了各观测物理量的特征值、变化规律和变化趋势。成果表明,各观测部位的应力、应变和渗流状态总体正常。

The prototype observation items of the power plant at Xikou pumped storage power station include strain of concrete, strain of sheet-metal casing, stress of steel bar, and seepage of sidewall and foundation. Based on the observation data from the date of embedment of instruments settlement to the end of 1999,the characteristic values and the regularities of the observed variations are analysed. The comprehensive evaluation shows that the operation situation of the power plant is normal.
