PARALLEL SPIRAL TRANSMISSION LINE USED IN GROUND DISPLACEMENT MEASUREMENT

摘要：

　　The monitoring of geological disasters has important significance for the protection of peoples personal safety,the national economy and peoples economy.The parallel spiral transmission line needs to combine the time domain reflectometry(TDR)to measure the displacement,and the main problem is to find the relationship between the tensile force and the characteristic impedance.Deformation sensors based on parallel spiral transmission lines are suitable for large deformation measurements.The structural characteristics and working mechanism of parallel spiral transmission lines are investigated.The relation between characteristic impedance and deformation of parallel spiral transmission line is obtained by electromagnetic field principle.
