THE MEASUREMENT AND STUDY ON IN SITU STRESS IN THE CENTRAL AREA OF THE HUANGCOU ACCUMULATION POWER STATION, HEILONGJIANG

摘要: 本文介绍了黑龙江荒沟抽水蓄能电站空心包体应力计地应力实测结果,对该区应力作用特征进行了分析。采用最小二乘法对地下厂房区4个测点测量结果进行综合计算,得出最大主应力近于水平,应力量值为9.6MPa,最大主应力方向为N78。W。这与该区新构造调查所表征的现今区域应力场比较吻合,同时也与中国东北部地区构造应力场具有一致性。

Abstract: Based on the results from in situ stress measurement in Huanggou Accumulation Power Station,Heilongjiang, the authors analyse the characteristics of the in situstress. The calculation of measurements from four sites in underground plant by method of least squares shows that the maximum principal stress is nearly horizontal with N78°W trending of 9.6MPa. The result is consistent with the present tegional stress field manifested by investigation of neotectonics, and also with the regional stress field in northeastern China.
