| Abstract: | This paper discussed in-situ stress measurements in boreholes of different directions around underground tunnel by hydraulic fracturing technique. Combining the measurements carried out at Tianhu andLongtan hydropower stations, and Guangzhou pumped storage power station, we analysed the distributionstate of stress in tunnel surrounding rock, and the main factors affecting the stress distribution in Surrounding rock. |
