摘要
从实际流体的运动微分方程出发,推导得出了破碎岩体中的气体渗流微分方程,并进一步结合流一固耦合理论导出了破碎岩体中的流—固耦合随机微分方程;通过自行设计的试验仪器、试验方法,进行了破碎岩体中的气体渗流试验,得出了不同粒径的破碎砂岩的气体渗透率,并给出了破碎岩体中的渗透率变化规律,丰富了破碎岩体中气体的渗流理论和试验方法,对以后该问题的进一步研究具有一定的参考价值。
In this paper, the differential equation of gas seepage of over-broken rock mass has been deduced, and furthermore its liquid-solid-coupling expression has been given. Besides, the permeability of over-broken sandstone has been obtained by experiment. Thus, the gas flow of over-broken rock mass theory has been validated. The preceding conclusions is to be a part of the theory of gas seepage, and has some regerence price for the studies of gas seepage later.
