本文根据实测地应力值回归获得的地下厂房区大范围的地应力场,分析了广州抽水蓄能电站地下厂房开挖时的围岩应力场及位移场,并对洞室围岩稳定性进行了评价。它是根据“广州抽水蓄能电站厂房区地应力测定及分析”一文(见《长江科学院院报》1988年第4期)提供的方法,在工程上的具体应用。
Based on the large-scale ground stress field obtained from the regression of measured in-situ stress, the stress field and displacement field of surrounding rock of underground powerhouse in Guangzhou Pumped Storage Power Station were analyzed. Evaluation. It is based on “Guangzhou Pumped Storage Power Plant Area Determination and Analysis of Ground Stress” article (see “Yangtze River Academy of Sciences,” No. 4, 1988) provides the method, the specific application in engineering.
