|
摘要
为研究岩石水力学和合理预测工程岩体中复杂的渗流状态,针对微型石灰岩试件天然裂缝三维应力作用下的渗透性进行了试验研究。利用太原理工大学多功能综合加载-渗透系统,在恒定渗透压和固定围压条件下,进行轴压变化对渗透影响的试验;在恒定渗透压和固定轴压条件下,进行围压变化对渗透影响的试验。
For the study of rock hydraulics and reasonable prediction of complex deep flow state in engineering rock mass, aimed at the micro limestone specimens of three-dimensional stress under the action of natural fracture permeability were studied.Use of taiyuan university of technology of science and multi-functional comprehensive load- infiltration system, fixed constant osmotic pressure and confining pressure conditions, axial compression on the impact of change on infiltration experiment was carried out; Under the condition of constant osmotic pressure and fixed axial compression, confining pressure on the impact of change on infiltration experiment was carried out.
