含水率对膨胀岩膨胀应变的影响研究

摘要

通过某铁路膨胀岩的室内试验研究,分析了膨胀岩在不同含水率状态下,膨胀岩的膨胀应变特征与过程,提出了起始膨胀含水率的概念.该概念具有相当的工程意义.%A railway through the swelling rock of the laboratory experiments, analysis of the swelling rocks in different water conditions, deformation characteristics and deformation process, and further proposed the initial swelling of moisture content.The concept has considerable engineering significance.
