Microseismic Monitoring and the Blasting Vibration on the Joint Control of Slope Stability

In order to study a high and steep rocky road slope during construction under the influence of blasting vibration in Guizhou. On the basis of discussing respectively the principle of microseismic monitoring and the blasting vibration,IMS microseismic monitoring equipment is used to explore the internal law of seismic activity of the slope rock mass under blasting vibration,at the same time,TC4850 blasting vibration is used to study the effect of blasting vibration on the surface of slope stability. The two methods are combined to take a joint control of slope stability during the construction. Results show that when the microseismic events of the inner region of slope rock appear densely,the vibration velocity of its corresponding rock mass surface particle is larger,the reliability of joint control is more stronger,the method is worth widely popularization in stability monitoring of excavation slope in the highway engineering.
