两种地应力测量方法在某抽水蓄能电站中的应用

Application of two geostress measurement methods to a pumped storage power station

简述了深孔套芯解除法三维地应力测量和水压致裂法测量地应力的试验方法及其在某抽水蓄能电站中的测试结果,并结合地下厂房和高压岔管区时地应力测试结果进行了分析。

The two methods for measuring geostresses, the hole-wall strain-gauge method and the hydro-fracturing method, are described briefly; and their applications to a pumped storage power station and measured results are also expounded. And the measured results of geostresses at an underground powerhouse and its high-pressure bifurcations, are analyzed and compared in detail.
