因为土体含水量会影响土体的物理特性,土壤含水率监测成为了岩土工程中一项重要的内容.目前市场上常用的TDR监测设备价格昂贵,且操作繁杂.文中根据时域反射技术原理(Time Domain Reflectometry,TDR)提出了低成本TDR设备土壤含水率集成监测技术.文中先是自主设计TDR元件,以降低工艺制造成本.然后编写MATLAB1.0分析软件进行数据自动分析.最后通过探针长度测量试验和土壤含水量测量试验,为TDR在土壤含水量测量方面的应用提供了参考.
EXPERIMENTAL STUDY ON SOIL MOISTURE CONTENT OF LOW-COST TDR EQUIPMENT
Since soil moisture content affects the physical properties of soil,soil moisture content monitoring has be-come an important part of geotechnical engineering. The TDR monitoring equipment commonly used on the market today is expensive and complicated to operate. Herein,an integrated monitoring technology of soil moisture content of low-cost TDR equipment is proposed according to the principle of time domain reflectometry (TDR). TDR compo-nents are independently designed to reduce process manufacturing costs,and automatic data analysis are carried out by MATLAB1.0 analysis. Finally,results from the probe length measurement tests and the soil moisture content mea-surement tests may provide the reference for the application of TDR in soil water content measurement.
