裂隙岩体中的渗流与岩体变形

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。

Seepage and Deformation of Fissured Rock Mass

Seepage law of fissured rock masses is presented in this paper. The Navier-stokes equation is demonstrated available to describe seepage law of rock masses by testing study. The dynamical seepage pressure in rock masses makes great effect on deformation of rock masses, results in opining of fissure and deformation of rock masses. The seepage and deformation of rock mass and dynamical seepage pressure is studied. The experimental results are checked with Bossiness formula, and are closed to the computing data.
