摘要
为了确定惠州抽水蓄能电站高压隧洞以及地下厂房围岩应力状态,利用应力解除法以及水压致裂法进行了地应力测量,并通过有限元回归分析,预测了包括重要工程部位在内的整个工程区岩体应力分布。
In order to determine the stress state at underground power house and pressure tunnel of Huizhou pumped storage plant, the in-situ stress measurements by hydro - fracturing method and overcoring method have been carried out. Also, the stress distribution in the whole rock mass including the major project locations was obtained through FEM regression analysis.
