| 摘 要： | 为了分析带边缘排水系统的排水性基层路面结构的排水效果,基于非饱和渗流理论,对高速公路路面结构降雨入渗进行数值模拟分析,建立了二维路面结构渗流分析模型,并采用AASHTO评价指标t50进行排水性能评价.结果表明:在没有内部排水系统的路面结构中雨水排出很慢,并会在基层与底基层中长时间滞留;带边缘排水系统的排水性基层路面结构...

| Abstract: | In order to analyze the drainage performance of the pavement structure with permeable base course and edge drainage system,based on the theory of unsaturated seepage,the rainfall infiltration into the highway pavement structure is simulated numerically and the two-dimensional seepage analysis model is set up.The AASHTO evaluation index t50 is employed to evaluate the drainage performance.The results show that,in comparison with the pavement structure without the internal drainage system,the water can be dra... |
