近几年来,公路运输事业有了很大的发展,汽车数量普遍增多,车重增大,交通量猛增,从而对公路提出了更高的要求。很多省、市地区都在修建或正在筹建高等级公路。因此,解决路基排水问题,已经成为重要的研究课题。本文就排除路基地下水问题提出一些设想,供同行们共同探讨。一、路基排水问题的提出依据高等级公路的优越性,首先从路面上反映出来。体现在路面能够满足车辆在高速状态下的安全性和舒适性。但是,高级路面必须依托在高质量的路基之上,也就是说,路 In recent years, there has been a great development in the road transport industry. The number of vehicles has generally increased, the number of vehicles has increased, traffic volume has soared, and highway requirements have been set higher. Many provinces and cities are building or are planning to build high-grade highways. Therefore, to solve the problem of subgrade drainage has become an important research topic. This article put forward some ideas to eliminate the problem of subgrade groundwater for colleagues to discuss. First, the proposed subgrade drainage problems based on the superiority of high-grade highways, first reflected from the road. Reflected in the road to meet the vehicle in high-speed state of safety and comfort. However, high-quality pavements must rely on high-quality subgrade, that is, roads
