摘要
随着我国沿海和中部地区经济高速发展,公路客货运输量也在迅速增长,既有高速公路扩容已十分必要和迫切。但高速公路造价高昂,其扩容改造往往牵一发而动全身,制约扩容方案的影响因素往往也非常复杂。高速公路扩容一般优先选择原路拓宽,对新建复线方案应慎重选择。针对海南环岛高速公路大三亚路段,从多方面对其扩容方案进行论证,对类似项目有一定的借鉴意义。
With the rapid development of economy in coastal and central China, the traffic volume of both passenger and freight have increased rapidly. In order to meet the needs of traffic growth in these areas, it is very necessary to expand the capacity of existing expressways, but the cost for expressway construction is high, and its expansion and widening often involve other aspects that to be affected, and the factors that restrict the expansion scheme are usually very complicated. The expansion of expressway generally prefers widening on the original route, and the added new route should be selected with discretion. In the paper, regarding to the Sanya Island Ring Expressway, the expansion scheme is demonstrated from many aspects, which has strong reference significance for similar projects.
