摘要
裂隙岩体的透水性各向异性和透水率大小的随机性 ,决定着渗控 (加固 )工程钻孔方位、倾角的多样性。它说明渗控工程设计中把裂隙岩体透水性假定成各向同性是不合实际的。应根据岩体的水文地质条件 ,寻找出裂隙隙宽、透水性和透水率相对较大的方位和倾角作为渗控工程钻孔的矢量。
The variability in orientation and inclination of drill for seepage control (reinforcement)engineering is determined by the anisotropy of permeability of jointed rockmass and random of permeability ratio,which also indicates that the assumption that the permeability of rockmass is isotropic is not actual in the design of seepage control.The vector of drill for seepage control should be determined from the joint width and orientation along which the permeability and its ratio are larger.
