| 摘 要： | 土石混合体属于典型的多孔介质,其渗透特性与砾石的体积分数关系密切.通过自制的常水头渗透仪,测定了不同含砾量时土石混合体渗透系数值,研究发现含砾量与土石混合体渗透系数之间存在指数关系;基于幂平均法,提出了土石混合体复合渗透系数的计算公式,并通过试验结果验证了该式的正确性,为土石混合体渗透系数的理论计算提供了一个简明有用的计算工具.

| Abstract: | Soil-rock-mixture is a typical porous medium,and its permeability is closely related to the content of gravel.By means of our own constant head permeameter,we have measured the permeability coefficients of soil-rock-mixtures with different gravel content,and the results show that there exists an index relationship between them.Based on the power averaging method,an empirical formula for the calculation of the composite permeability coefficients of soil-rock-mixture was proposed,and the formula was verified with the experimental results,thus offering a concise and useful computational tool for the theoretical calculation of soil and rock-mixture permeability coefficients. |
