本文引用岩体渗透水平极图的概念,从基岩各向异性的实际出发,将基岩透水(吸浆)有效影响范围概化为以灌注钻孔为中心的椭圆,提出了水电等工程基岩灌浆设计优化布孔的一种方法(椭圆法)。它较视单孔灌注范围为圆形的布孔方法(圆形法)更为经济合理。
This paper refers to the concept of rock mass infiltration horizontal pole figure. Based on the actual anisotropy of bedrock, the effective influence range of base rock permeability (suction) is generalized as ellipse centered on perfusion drilling. A method of optimizing grouting in rock grouting design (ellipse method). It is more economical and reasonable than that of a single-hole perfusion method (round method).
