| 摘 要： | 土石坝的渗流场是由饱和与非饱和渗流区组成的统一体,由于受测定非饱和土渗流参数的试验设备限制,考虑非饱和区的土石坝渗流分析在实际工程中应用不多.本文根据国外实验室测定的体积含水量曲线,结合国外研究者提出的体积含水量曲线、渗透性函数的估算方法,在考虑非饱和区的情况下,对均质土坝的稳态渗流、瞬态渗流进行了分析与比较,得出一些粗浅的看法,以供探讨.

| Abstract: | The seepage field of an earth-rock dam is an integration of saturated zone and unsaturated zone.The analysis of test data that cover only the saturated zone due to the limitation of test facilities is rarely applied to a practical design. This paper analyzes and compares the steady seepage and transient seepage of homogeneous earth dams under the conditions of unsaturated zone and draws some preliminary conclusions,by using the soil-water characteristic curve experimentally obtained in overseas laboratories... |
