In order to effectively respond to the global climate change and energy crisis, the structural transformation of energy has become an irreversible trend in the future development of China’s energy system. As a new kind of clean and renewable energy source, wind power technology has made great progress in recent years and has become relatively mature. The penetration rate of wind power in China’s power system increases continuously, playing an important role in promoting energy saving and emission reduction. However, because of their instability in time and space, wind power and solar power may pose great challenges to the safety of the power grid. To ensure power supply, thermal power generating units, combined with pumped-storage power stations, are still mainly used for peak load regulation nowadays, which is inconsistent with the long-term goal of carbon neutrality. This essay mainly studies the feasibility of turning hydropower stations into power regulation centers, taking the Three Gorges Project as the analysis object.

The time-dependent behavior of rock mass, which is generally governed by joints and shearing zones, is of great significance for engineering design and prediction of long-term deformation and stability. In situ creep test is a more effective method than laboratory test in characterizing the creep behavior of rock mass with joint or shearing zone due to the complexity of field conditions. A series of in situ creep tests on granite with joint at the shiplock area of the Three-Gorges Project and basalt with shearing zone at the right abutment of the Xiluodu Project were performed in this study. Based on the test results, the stress-displacement-time responses of the joints and basalt are analyzed, and their time-dependent constitutive model and model coefficients are given, which is crucial for the design to prevent the creep deformations of rock masses from causing the failure of the operation of the shiplock gate at the Three-Gorges Project and long-term stability of the Xiluodu arc dam.
