基于C-DTS的土壤含水率分布式测定方法研究
Distributed method for measuring moisture content of soils based on C-DTS
摘要
Abstract
Based on the carbon-fiber-heating-cable distributed temperature sensing system (C-DTS), a new distributed method for measuring the moisture content of soils is proposed. The temperature of soil-buried-cable is measured by C-DTS in this method. The moisture content of soils is determined by the relationship between the temperature characteristic value (Tt) and the moisture content. Tt is defined, and it is proved that there is a linear relationship between the moisture content and Tt. The relevant parameters can be determined by calibration experiment. The experimental results show that the moisture content of soils can be measured effectively through artificial heating carbon-fiber-cable, and the usage of DTS provides distributed measurement. The accuracy of this method is related to the section of Tt. The success of the proposed method provides a very advanced distributed approach for measuring the moisture content of soils. Further improvement and popularization are required.关键词
