库岸边坡变形场与水分场光纤监测技术研究
Study on optical fiber monitoring technique of deformation field and moisture field of bank slope
摘要
Abstract
Landslide hazards occur frequently in the Three Gorges Reservoir area.Therefore,it is of great importance to use highly efficient landslide monitoring techniques to prevent and mitigate these hazards.This paper describes three optical fiber sensing technologies,i.e.,ROTDR,BOTDR and FBG,and the corresponding landslide deformation field and moisture field monitoring techniques.Taking the Majiagou #1landslide as an example,the DFOS-based monitoring scheme,the layout of sensors,and the method for fiber protection are introduced,and the monitoring results of deformation field and moisture field are analyzed.The monitoring results show that it is feasible to apply DFOS technology to deformation and moisture fields monitoring of reservoir landslides,which can provide a new method for investigating the evolution mechanism and early warning of reservoir landslides.关键词
