【摘要】 在千将坪滑坡前地震动事件分析基础上,总结滑坡前滑坡体内部岩体形变和破裂所产生地震信号的典型特征,并建立宽频带地震台,对金坪子滑坡体和早谷田危岩体进行监测实验,提取基岩类、土质类和危岩体类3种基本物质组成滑坡的微振动前兆信息特征,为地震台网在滑坡监测预报中的应用推广和监测预报系统软件的研制奠定基础。根据测震学原理,研发滑坡监测分析系统软件(Smas),可为滑坡大规模活动前快速预警。更多还原

【Abstract】 Based on analysis of seismic event before Qianjiangping landslide,the authors have summed up the typical characteristics of seismic signals generated by the internal rock mass deformation and fracture before landslide,and have established a broadband seismic station network to carry out monitoring experiment on Jinping landslide and early crop dangerous rock,from which the authors extracted the bedrock,soil and dangerous rock,and these three basic material consist of micro-vibration precursor information characteristics of landslide.All these lay a solid foundation for seismic network in the application of landslide monitoring and prediction and the development of monitoring and forecasting system software.According to the principle of seismometry,the author developed a set of landslide monitoring and analysis system(Smas) software,which has the characteristics of real-time and automation,and can also send landslide precursor information to relevant personnel of by means of SMS in the case of unattended condition(such as night),so as to achieve rapid alert prior to the landslide mass activities.更多还原
