文章通过理论分析与数值分析相结合的方法,首先定量分析了折减系数取值规律;然后研究了排水孔对等效渗透系数的影响。对于衬砌外水压力的定量分析有一定参照意义。
Through the combination of theoretical analysis and numerical analysis, the article first quantitatively analyzes the law of the value of the reduction factor; and then studies the effect of drainage holes on the equivalent permeability coefficient. It is of certain reference significance for the quantitative analysis of lining external water pressure.
