Paper Number: ARMA-2023-0636
... has not been understood well. In this paper, a 3D full-scale hydropower station is built by FLAC3D, and several sets of seismic waves based on the real earthquake motions are applied from different excitation direction. The results show that the wave excitation direction directly influences the result...

... powerhouse at the Houziyan hydropower station and a damage-driven numerical model based on MS data is adopted to quantify the surrounding rock mass damage. The rock mass is degraded and simulated by a micromechanics-based constitutive model described by the fracture density, which is determined by the amount...

... Abstract A serials of loading-unloading experiments of marble in Jinping II hydropower station, China, are carried out to investigate its failure mechanism under complex stress condition. It is found that, the marble failure process is divided into five stages, including initial crack closure...
