中文摘要：
为研究贵州某高陡岩质公路边坡在施工期间受到爆破震动的影响,在分别探讨了微震监测和爆破测振原理的基础上,用IMS微震监测设备探索爆破震动下边坡岩体内部微震活动规律,TC4850爆破测振仪研究爆破震动对边坡表面稳定性的影响,两者结合,对施工期的边坡稳定性进行联合控制。结果表明,微震事件集中分布的岩体内部区域对应的岩体表面质点振动速度较大,联合控制可靠性更强,值得在公路工程开挖边坡稳定性监测中广泛推广。
英文摘要：
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.
