چکیده
As the hydropower development strategies of China continue to be implemented, a host large projects have been completed or are being constructed in southwest China. During construction Jinchuan station, this study examined stability surrounding rock during excavation and unloading hydraulic tunnels under demanding geological conditions. Microseismic (MS) monitoring technology was employed monitor deformation failure online real time, based on engineering data site surveys. To analyze spillway tunnel temporal spatial evolution characteristics MS events, source parameter analysis numerical modeling were performed. The 3D finite-difference software FLAC3D used simulate mechanical response diversion tunnel. results compared with surveys determine mechanisms tunnels. research can serve as guide for studying similar

Hydraulic Transients in the Long Diversion-Type Hydropower Station with a Complex Differential Surge Tank
Based on the theory of hydraulic transients and the method of characteristics (MOC), a mathematic model of the differential surge tank with pressure-reduction orifices (PROs) and overflow weirs for transient calculation is proposed. The numerical model of hydraulic transients is established using the data of a practical hydropower station; and the probable transients are simulated. The results ...

Analysis of Face Stability during Excavation of Double-O-Tube Shield Tunnel
This paper focuses on the face stability analysis of Double-O-Tube shield tunnel. This kind of analysis is significant to ensure the safety of workers and reduce the influence on the surrounding environment. The key point of the stability analysis is to determine the supporting pressure applied to the face by the shield. A collapse failure will occur when the supporting pressure is not sufficie...
