Analvsis of Impact Factors and Change Laws for Double-ring Measuration on Hydraulic Conductivity
Hydraulic conductivity is one of the important hydraulic characteristic parameters of soil, and there are many methods to measure, one of which is double-ring method widely used in China. Aiming at the main problems of the double-ring experiment on hydraulic conductivity, the mathematical model of double-ring measuration is built up. Based on the numerical results, the paper analyzes the influence on measurement accuracy laws of the factors, including inner ring radius, insertion depth, constant water head and radio of outer ring radius and inner ring radius and puts forward the modified formula for different head and the way to determine the optimum scheme for the double ring experiment.
