介绍了在模型槽试验中应用TDR测试技术测试土体的含水量测试。试验结果表明,TDR测试技术可以在模型槽试验中很好地测得土体的含水量,并能随时反映土体含水量的变化,研究成果对于大型试验中的土体物理参数的监测具有重要的意义。 This paper introduces the test of water content of soil by using TDR test technique in the model groove test. The test results show that the TDR test technique can well measure the soil water content in the model tank test and reflect the change of soil water content at any time. The research results are important for the monitoring of soil physical parameters in large-scale experiments Meaning.
