摘要
应用岩石力学试验系统,对奥陶系顶部峰峰组灰岩进行岩体水—岩耦合试验,分析在不同围压和渗透水压条件下,灰岩的强度变化规律、灰岩的变形程度和渗透率变化规律,研究灰岩在应力场与渗流场综合作用下渗透性的变化情况,分析峰峰组灰岩的相对阻隔水性能。
By using the rock mechanics testing system,the water-rock coupling test of rock mass was carried out on the Fengfeng Formation limestone at the top of Ordovician.The strength change law,deformation degree and permeability change law of limestone under different confining pressure and osmotic water pressure were analyzed.Limestone permeability changes under the combined action of stress field and seepage field were studied comprehensively,and the relative water barrier performance of the Fengfeng Formation limestone was also analyzed.
