本文介绍裂隙岩体的渗流规律。我们通过试验认为应用纳维-斯托克斯(Narier-Stokes)方程描述岩体的渗流规律是可行的。岩体中的渗透动水压力对岩体的变形有重要的影响,渗透动水压力导至裂隙的张开、岩体变形,并影响岩体的稳定性。裂隙的张开引起渗流量的增加。我们应用原位(现场)试验的方法测量岩体的变形和渗流量,并研究渗透水压力与岩体变形的关系。试验成果用布希内斯克(Boussinesq)公式检查,表明其与计算结果比较接近。本文的原位试验为解决复杂的渗流问题提供了一个初步的研究方法。
This paper introduces the seepage law of fractured rock mass. We have experimented that it is feasible to apply the Narier-Stokes equation to describe the seepage law of rock mass. The osmotic pressure of water in the rock mass has an important influence on the deformation of the rock mass. The osmotic water pressure leads to the opening of the fracture and the deformation of the rock mass, and affects the stability of the rock mass. The opening of the cracks causes an increase in percolation. We used in-situ (in situ) tests to measure the deformation and seepage of rock mass, and to study the relationship between the pressure of infiltration water and rock mass deformation. The test results were checked with the formula of Boussinesq, which showed that it was close to the calculated results. The in-situ test in this paper provides a preliminary research method for solving complex seepage problems.
