摘要
介绍了一种新研制的可以测定松散土体真实给水度和毛细负压值的实验仪器,它能测定天然状况下原状土体的给水度和毛细负压值,并能很好的反映出给二者随地下水位埋深变化的特点。选做的均质土体的给水度和毛细负压值测定实验,验证实验仪器的可靠性和实用性。
The paper introduces a new apparatus which can measure the specific water yield and capillary value of incompact soil.It can not only measure the specific water yield and capillary value of the original state soil under the condition of natural situation,but also can reflect them the changeable characteristics of the value with groundwater level variation.For testing the reliability and practicability,we choose a homogeneous soil as an example.The result of the test shows there is a wonderful effect.
