Paper Title:
Numeric Simulation of Fracture Extension within Surrounding Rock under Continuous Excavation
  Abstract

This paper aims at progressive failure within surrounding rock under continuous excavation, such as mining, underground powerhouse building, etc. A meso-damage model is proposed, which include the damage law under complex stress state for brittle materials, and the damage evolution based on stiffness degradation. The damage model is embedded into the FEM program. To test and very the damage model, a example of continuous excavation of underground mining is simulated. The result shows that the crack field growth is in accordance with that the similar material experiment.
