Re-analyzing the in-situ stress field in the right bank of the Baihetan hydroelectric power plant using the borehole breakout data

The Baihetan hydroelectric power plant, located on the Jinsha River in the Sichuan-Yunnan Block, Southwest China, is the second largest after the Three Gorges hydroelectric power plant. Crustal stress state is an important geological factor affecting underground engineering, and the stability analys...
