刺桐路北拓～洛江、惠安西片区快速通道工程方案关键技术研究

Key Technical Problems Research for Citong Road Northbound Extension Line to Luojiang,Huian West Area Fast Channel Design

近些年来,以城市快速路及快速轨道交通为代表的城市快速交通迅猛发展,满足了大中型城市人员、货物快速流动的需求,实现了城市交通整体水平的提升,也保障了城市经济社会的发展。城市快速路线位的选择应本着"环保选线、地质选线、技术指标与地形条件相协调"的原则,正确处理项目建设与自然景观、人文景观的关系;对于立交节点方案的确定应以满足交通功能需求为基本原则,尽量节约用地,有效利用空间。本文以福建省泉州市一条位于丘陵区地形的快速路-刺桐路北拓～洛江、惠安西片区快速通道作为设计实例,对于城市快速路的关键性技术问题,如路线的比选、立交节点方案的确定进行探讨研究。

The city expressway and the rapid rail transit, as the representatives of urban rapid transit, have been developed vigorously in recent years. The urban rapid transit can satisfy the rapid flowing needs of people and goods in large and medium-sized cities, realize the improvement of the overall level of urban traffic, and ensure the development of urban economy and society. The selection of city expressway route position should be based on the principle of ＇~＇ environmental route selection, geological route Selection, technical indexes and topographic conditions coordinated＂ to correctly handle the relationships between project construction, natural landscape and cultural landscape. For the determination of interchange node scheme, we should make it meet the traffic function demand as the basic principle, save land as much as possible and make use of space effectively. An expressway located in hilly region of Quanzhou, Fujian province, known as a fast channel from Citong Road northbound extension line to Luojiang, Huian west area, was set as a design example in this paper. Then, the key technical problems such as route selection and determination of interchange node scheme for urban expressway, were discussed and researched.
