| Notes | 45-1157/P GUAN Zhen-de, JIANG Xiao-zhen, GAO Ming （Institute of Karst Geology, CAGS, Karst Dyna mics Laboratory, MLR ＆ GZAR , Guilin, Guangxi 541004, China） karst collapse; distributed optical fiber sensing; sinkhole collapse model device; monitoring; experiment In line with the deformation characteristics of the sinkhole collapse, the mechanic relation between the soil body and the sensing fiber is analyzed, the mechanic model of collapse is simplified, and simulation test device is processed and tested. Firstly, the sinkhole formation process is stimulated with the orderly changes under load on the optical fiber. And then, the impact of the changes in sinkhole size on the sensing fiber monitoring is analyzed. The study shows that the key factors affecting the application of the technology include the stress field distribution changes led by overlying loads and hole size change during the formation of the holes, and the difference of responding sensitivity to the stress field change among different optical cabl |
