摘要 针对TDR(时域反射法 )技术在边坡监测中的应用 ,阐述了TDR边坡监测系统的组成及测试原理 ,建立了TDR测试系统的计算模型。结合试验数据 ,应用反馈系统理论计算分析了电磁波在同轴电缆中的传播特性及同轴电缆的剪切变形对TDR波形的影响 。 According to the applications of TDR technology to slope monitoring,components and measuring principles of time domain reflectometry(TDR) system are described herein and a calculation model of TDR measuring system is given.Based on experimental data,the feedback system theory is used to calculate and analyze the properties of electromagnetic wave propagation in coaxial cable and the influence of coaxial cable′s shear deformation on TDR signal,which validates the rationality of the calculation model given in this paper.
