摘要

根据我国西部不同气候、地形地貌因素，将有关农田水利排水的渗流模型引入了公路路基排水，重点研究了完整盲沟的无降雨渗流模型、连续降雨入渗模型、降雨停止后渗流模型、阶段性降雨模型及其解析解。通过工程实例，运用连续降雨入渗模型和降雨停止后渗流模型，计算了路基内部盲沟的设置间距和排水时间，实践证明该方法是有效的，为西部公路盲沟排水设计中的排水计算提供了一定依据。

Abstract

Based on different conditions of climate and landforms

the mathematic models of seepage in farm drainage are used for drainage inside roadbed of expressway; and the seepage model without considering rainfall

seepage model with considering lasting rainfall

seepage model after stopping rainfall

seepage model with phase rainfall of full blind drainage and their analytic solutions are studied emphatically. It has been proved by engineering cases that the drainage design with seepage model is reasonable so as to provide definite experiences for drainage design of blind drain inside roadbed of expressway in the West China.
