水压致裂及其三维应力分析在张河湾蓄能电站中的应用
Stress Measurement by Hydrofracturing and its 3-Dimensional Analysis Applied to Zhanghewan Store Energy Hydropower Station
【摘要】 <正> 一、前言张河湾抽水蓄能电站位于河北省石家庄市井陉县测鱼镇南甘陶河干流上,距石家庄市90km。该电站利用已建的张河湾水库做下库,在坝上游1.2km的左岸老爷庙山顶建上库,上下两库水平距离500m,相对高差350m。预计电站装机容量100万kW,是冀南电网的主要调峰电站。电站设计中需认真考虑地下厂房与各类硐室群的稳定,上库蓄水后对原生裂隙及各种软弱带的影响,以及地下硐室群的岩爆和衬砌等与原地应力的关系。因此,在电站初设阶
【Abstract】 Based on the principle of in-situ stress measurement by hydrofracturing technique and the algorithm of its 3-dimensional analysis,three deep boreholes and four shallow ones in the Zhanghewan Store Energy Hydropower Station region have been tested,and the relevant data of the crustal stress field obtained.Some stress problems which the project designing department pays close attention to are also discussed in this paper.
