摘要：在土体中进行时域反射计（TDR）试验的波形取决于试验土体的温度。该研究针对用于计算土体含水量和干密度的TDR试验中所测参数的温度校正给出了一个讨论和校正原则。本文是另一篇文章的姊妹篇，另一篇文章给出了更新后的美国材料试验协会标准，但其没有包含温度的影响。鉴于识别参数对试验土体的温度很敏感，本文给出了该新方法的概述。

Abstract: The waveforms from time domain reflectometry (TDR) tests on soil depend on the temperature of the soil being tested. This study provides a discussion of, and the basis for, temperature corrections for the parameters measured in the TDR test for use in calculating water content and dry density of soil. This paper is a companion to one that provides the basis for an updated ASTM Standard, but does not cover temperature effects. A brief synopsis of the new methodology is provided herein to identify parameters that are sensitive to temperature of the soil being tested.
