岩溶塌陷具有的突发性、隐蔽性、不确定性,使其监测、预警预报问题一直未解决。通过多年的研发,光纤传感器监测技术已成为当今最为先进的岩土变形现场监测技术,特别是BOTDR技术,它的分布式、长距离、远程实时监控以及光纤耐久性好的特点正好弥补了传统监测技术的不足。目前光纤传感技术在岩溶塌陷(沉陷)灾害的监测上开展工作较少,本次工作主要目的为利用光纤传感技术实时监测岩溶塌陷。
Karst collapse with the suddenness, concealment, uncertainty, to make it monitoring, early warning and forecasting problems have not been solved. Through years of research and development, optical fiber sensor monitoring technology has become the most advanced on-site monitoring technology for geotechnical deformation, especially the BOTDR technology. Its distributed, long-distance, remote real-time monitoring and good optical fiber durability make up the traditional monitoring Lack of technology At present, optical fiber sensing technology has less work on the monitoring of karst collapse (subsidence) disaster. The main purpose of this work is to use optical fiber sensing technology to monitor karst collapse in real time.
