This paper briefly describes the defects of the ground collapse measurement technology at present and proposes a new method for measuring the ground collapse. The structure of the spiral parallel cable is illustrated and its circuit characteristics are deduced,it is concluded that the characteristic impedance increases with the increase of tensile deformation,and the dielectric constant has little effect on the characteristic impedance. TDR method combined with spiral parallel cable can be applied to the measurement of ground collapse.Tensile deformation reflects the extent of ground collapse,and the position of the peak of the reflection signal is the location of the ground collapse deformation. In the end,the mathematical model of the UVE-PLS which sets up the relationship between the tensile deformation and the reflection signal is established,and gets accurate prediction results.
