【摘要】：公路中水的来源主要包括地下水、地表水侵入和大气降水三个方面。水不仅影响公路行车安全,而且会缩短道路使用寿命。路面上的水会造成路面湿滑,车辆行驶打滑、刹车距离增大;路基、路面中渗入的水会造成路基、路面结构的损坏,减少公路使用年限。如何解决水对公路的损害问题,以及如何有效的减轻水所带来的危害是这篇论文主要研究的方向。本论文以呼和浩特至包头段高速公路为依据,深入研究呼和浩特和包头地区的水文地质、水流形成原理,并且对大气降水、地下水以及地表水入侵对公路的影响进行归纳、整理、分析。并且在现有公路排水方式的基础上,结合呼和浩特至包头四车道改八车道高速公路设计过程中的路基、路面排水方案,对公路工程路基、路面排水工程提出了切合实际、适应性强的排水方案。这些方案具有更好的代表性和实用性。在现行规范以及水文学、水力学研究成果基础上,对呼和浩特至包头段高速公路排水系统的汇水面积、设计降雨重现期等设计参数进行详细调查、计算和分析,对边沟、排水沟的尺寸、坡度、长度,集中排水拦水带开口间隔等数据进行计算。参考最新蒸发池计算方法,对互通式立交圈内蒸发池尺寸予以确定。对国内外的先进设计理念予以研究,以更加先进的方式去系统的分析整个呼包高速公路环境中的所有主要的排水方式。
[Abstract]:The sources of water in highway include groundwater, surface water intrusion and precipitation. Water not only affects the road safety, but also shortens the service life of the road. The water on the road will make the pavement slippery, the vehicle will slide and the braking distance will increase; the water infiltrated in the subgrade and pavement will cause the subgrade, the pavement structure will be damaged, and the service life of the highway will be reduced. How to solve the problem of water damage to highway and how to effectively reduce the harm brought by water are the main research directions of this paper. Based on the highway between Hohhot and Baotou, this paper deeply studies the hydrogeology and the formation principle of water flow in Hohhot and Baotou area, and sums up the influence of precipitation, groundwater and surface water intrusion on highway. Sort out and analyze. And on the basis of the existing highway drainage methods, combined with the roadbed and pavement drainage scheme in the design process of Huhehaote to Baotou four-lane to eight-lane expressway, the roadbed and pavement drainage works of highway engineering are put forward in accordance with the reality. An adaptable drainage scheme. These schemes are more representative and practical. On the basis of current specifications and hydrology and hydraulic research results, the design parameters of drainage system of expressway from Hohhot to Baotou are investigated, calculated and analyzed in detail. The size, slope, length and opening interval of the drainage channel are calculated. According to the latest calculation method of evaporator, the size of evaporator in interchange ring is determined. The advanced design concepts at home and abroad are studied, and all the main drainage methods in the environment of Hu-bao freeway are systematically analyzed in a more advanced way.
