本文介绍了使用改制的膨胀实验装置,对两种膨胀岩的力学特性所进行的研究。根据实验结果,结合工程实例,对膨胀岩巷道由于吸水膨胀而产生的应力和位移进行了计算分析。
This article describes the use of a reconstructed expansion test device to study the mechanical properties of two types of swelling rock. According to the experimental results, combined with engineering examples, the stress and displacement caused by the expansion of water in the expansive rock roadway are calculated and analyzed.
