摘要

Researched the law of energy transfer when the tunnel deformation and failure considering supporting conditions and material strength. Using RFPA software calculated deformation and failure characteristics of deep burying tunnel, the authors analyzed mechanism of deformation and failure of the tunnel from the point of view of energy release, explored the law of elastic energy accumulation with the strength of material and supporting strength changing by numerical calculation. For the study of deep tunnel rock deformation and dynamic disaster induced by damage provided prediction method, for deep tunnel excavation and the reasonable safety supporting provided the reference.
