Paper Title:
Preliminary Study on Shear-Flow-Creep Experiment for the Fracture of Hard-Rock
  Abstract

The nuclear waste storage projects, hydropower and etc are often installed in the hard crystalline rocks. The creep phenomenon of the hard rocks appears in virtue of the complex geological conditions, especially when the excavation brings about damage and cracks to the rockmass, and they largely weaken the hydraulic performances of surrounding rock. Once the excavation-caused cracks are well connected with the native ones together, the engineering safety will be brought great harm to. By dint of newly developed shear-flow-creep coupled experiment system, on condition of the constant normal stiffness boundary conditions, the coupled shear-flow-creep tests are conducted. Not only the tests testify that the equipments is reasonable and effective and the creep largely influences the seepage performance of the rock crack, but also the coupling characters are primarily proved up.
