【摘要】 简要介绍了布里渊散射光时域反射测量技术(简称BOTDR)在工程监测方面的最新发展,并结合具体的滑坡监测方案,讨论了该技术应用在滑坡预警中的可行性。目前的研究成果表明,该技术具有常规监测技术所不具有的诸多优点,如分布式、长距离和实时性等,可满足滑坡早期预警和防护工程安全监测要求,同时仍有许多相关课题有待研究,如温度影响、铺设技术和疲劳效应等等。更多还原

【Abstract】 The newest development of Brillouin Optical Time Domain Reflectometry (BOTDR) application in largeinfrastructure engineering monitoring is presented. Based on the monitoring characteristics of landslide early-warn-ing, BOTDR’s application feasibility to the early-warning of landslide is discussed. It is demonstrated that BOTDRis outstanding with its distributed monitoring, long distance and real-time monitoring, so that it fully meets the de-mand of the early-warning of landslide and health monitoring of slope project. However there are still many rela-tive topics to study such as temperature impact, installation methods of fiber optic sensor, fatigue effect of optical fi-ber.更多还原
