Formatted Abstract/Summary
在很多情况下,为了评估结构构件(例如密封件)的功效或者系统的稳定性,土木工程师对表征土工建筑物水力状态的定性或者定量的含水量分布情况比较关注。时间域反射法(TDR)是一种测量含水量的方法,这种方法被广泛应用于水文学和土壤物理学中。此方法在土壤中埋设对湿气敏感的传输线(素石电缆)。在传感器上施加电磁脉冲,通过时间域反射计记录反射数据。利用TDR反射数据进行反演,可确定传输线周围的含水量和土壤的介电性能随空间变化的特性。这一新方法首次应用于全尺寸堤防模型中,第一次全程监控了瞬时水流流动过程。同样,传统的TDR方法也能达到监控堤防或大坝的目的,评估结构构件的效果,如上游止水设备。本文将介绍这两种方法的应用前景。

In many cases, in order to assess the structural components (eg seals) the efficacy or stability of the system, civil engineers, geotechnical characterization of the building on the water status of the qualitative or quantitative more concerned about the distribution of water content. Time domain reflectometry (TDR) is a method of measuring water content, this method is widely used in hydrology and soil physics. Buried in the soil, this method is sensitive to moisture transmission line (Su Shi cable). Electromagnetic pulse is applied to the sensor by time domain reflectometry recorded reflection data. The use of TDR reflection data inversion to determine the water content around the transmission line and dielectric properties of soil properties with the spatial variation. This new method was first used in the full-size model of the dike, the first full monitoring of the transient water flow process. Similarly, the traditional TDR method can also achieve the purpose of monitoring the dike or dam to assess the effect of structural members, such as the upstream sealing equipment. This article describes two methods of application.
