| 摘 要： | 对于深埋隧洞,由于高地应力和高水压环境,隧洞通过较宽的裂隙就可能发生较大的突水和涌水,而此时水在裂隙中的流动是处于非线性状态,因此开展了光滑平行板高速非达西渗流实验研究.详细介绍了光滑平行板的实验装置和实验步骤,通过对实验数据整理,利用Forchheimer形式的高速非达西渗流运动方程进行曲线拟合,得到每种隙宽的非达西影响系数、渗透率和方差,最终得到本实验的非达西渗流影响系数与渗透率之间的表达式,最后分析了实验产生误差的原因.

| Abstract: | For the deep tunnel,under high stress and high pressure environment,water inrush may be occured when the tunnel through the wide fracture;and water flow in the fracture was in a nonlinear state.So,the smooth parallel plate experimental study of high speed non-Darcy flow was done.The experimental setup and experimental procedure were described.Utilizing Forchheimer equation of high speed non-Darcy flow equation of motion,the influence coefficient of non-Darcy flow,permeability and variation of each fracture were obtained through the experimental data and curve fitting.The expression of the influence coefficient of non-Darcy flow and permeability was obtained for this experiment.Finally,the reasons of error in this experiment were analyzed. |
