A Damage Rate Formula before and after Blasting of Surrounding Rock Based on the Characteristics Stress Points

Zhang Yihai;Li Miao;University of Science and Technology Beijing,College of Civil Engineering and Resource Engineering;  
Nowadays blasting is used in most tunnels excavation and explosive impact stress will cause varying degrees of damage to the surrounding rock of the tunnel.The accumulation of damage will reduce the strength of surrounding rock and will reduce the stability.The process of rock failure is that the microcrack of internal defects develops,though the rock internal micro crack damage is difficult to be observed.All typical stress points of the stress-strain curve are obtained by indoor rock compressive tests and acoustic emission tests to determine the stage of microcrack development.Typical stress points have microcrack initial stress-the original rock damage strength,blasting stress-Kaiser point strength,microcrack coalescence stress strength-the original rock strength and the peak of compressive strength.Based on the study of the typical stress points the process of surrounding rock,the ratio formula of surrounding rock blasting is put forward,and the tunnel rock damage relative to the original rock is quantified.
