Laboratory Experimental Study on Seepage in Karst Depression Based on DTS
Karst depression is an ideal place for the construction of reservoirs,but most of the karst depressions are located in the strong karst development area,and there is a problem of karst leakage.Among various leakage monitoring methods,distributed optical fiber temperature sensing technology(DTS)has significant advantages.By analyzing the temperature performance law of the two types of optical cables under the same leakage conditions,the temperature characteristic value of the heatable optical cable under different media and heating power,and the leakage sensing range of the heatable optical cable,the effect of improving the leakage sensing ability of the heated optical cable along the PVC pipe spiral winding process is verified.The research results can provide reference for the application of DTS in seepage monitoring in karst depressions.
