广深高速鹤洲立交改扩建技术

Reconstruction and Extension Technology of Hezhou Interchange in Guangzhou – Shenzhen Expressway

高速公路的互通与立交枢纽形式多样,地理环境、建设条件差异明显。该文介绍了广深高速鹤州立交改扩建技术,认为:互通与立交的改扩建必须因地制宜,在充分研究路网规划和立交扩建条件的基础上进行针对性设计。互通立交的改扩建在尽量满足交通流的需求下,应合理确定改扩建方式,在考虑建设规模、安全性、工程经济、实施难度、景观设计等多方面因素的前提下,应着重减轻施工期对现行高速公路和地方交通、经济的干扰,最大限度地满足各项要求。

There are many types of interchanges and grade separations with the obvious different geographical environments and construction conditions in the expressways.The article introduces the reconstruction and extension technology of Hezhou Interchange in Guangzhou – Shenzhen Expressway.The reconstruction and extension of interchange and grade separation must suit the local circumstances.On the basis of fully studying the road network planning and the grade separation reconstruction extension conditions,the designs are specially carried out.The reconstruction and extension of interchange as satisfies the demand of traffic volume as possibly,and the reconstruction and extension mode should be reasonably determined.Under the premise of considering the construction scope,safety,engineering economy,implementing difficulty,landscape design and so on,the article introduces the focus on reducing the interference of construction period on the current expressways,local traffic and economy.It should satisfy various requirements to the maximum extent.
