摘要:Abstract: Sinkhole collapse at home and abroad in the distributed monitoring and forecasting have not yet successful applications, implementation in the field and no mature experience, field optical fiber monitoring only reflects fiber strain distribution and change, and we really need is specific soil settlement. Therefore, we need to build the relationship in fiber-optic strain and soil deformation, through fiber-optic strain can intuitively reflect the size of soil deformation. The main purpose of this experiment is reproducing the whole process of development of sinkhole collapse under different conditions indoor through physical model experiment, in order to establish the relationship in the settlement of soil deformation and fiber strain, and then research the critical condition of sinkhole collapse development, to guide the field monitoring and achieve early warning and forecast results.
