Abstract采用恒定水头法对土石混合介质的饱和导水率进行测定,分析不同碎石含量及碎石直径对饱和导水率的影响,同时利用实测值对Peck-W atson及Bouw er-R ice两个传统估算方程的估测精度进行比较。结果表明:(1)饱和导水率随碎石含量先增大后减小,且两者呈二项式关系;(2)饱和导水率随碎石直径增大而减小,两者呈幂函数关系;(3)碎石直径介于1.0~5.0 cm时,Bouw er-R ice和Peck-W atson方程对饱和导水率的估算结果均大于实测值。
Other AbstractBased on the experiment of the constant head method for saturated hydraulic conductivity,the effects of soil-stone ratios and stone sizes on K_s were studied.Meanwhile,we calculated the K_s with Peck-Watson and Bouwer-Rice equations respectively,then compared the results with the measured data.The results show that: K_s firstly decreases with the increases of the stone contents,and then increases.The relation between them follows binomial function;K_s decreases with the increases of the mean diameters of th...
