运用新奥法理论，对江垭地下水电站主厂房洞室在施工过程中的围岩稳定性进行了计算；并结合原始的变形观测值作了进一步分析验证．介绍了对不稳定块体的工程处理措施．指出在工程实践中严格遵守新奥法施工原则和加强变形观测对于维护高边墙围岩稳定的重要性．
The new Austrian theory was applied to calculate the surrounding rock stability of the main cavern of the Jiangya underground hydropower station during the construction process. The original deformation observation value was used for further analysis and verification. The engineering measures for unstable blocks are introduced. The importance of strictly observing the construction principle of New Austrian Law and strengthening deformation observation in engineering practice is pointed out.
