摘要
针对丽水港温溪作业区陆域多山地形导致的土地资源短缺现状,对疏港道路和后方高速公路的关系、疏港道路接入330国道方式以及疏港道路沿程各相关方如何接入等问题进行研究;提出对省道进行改线扩展陆域纵深的建设思路,改线后采用爆破开挖和机械开挖相结合的方式进行深挖路堑施工,以降低疏港道路对高速公路的影响,通过隧道内设置互通与国道进行连接,根据沿程各方的接入高程进行道路高程设计。在复杂周边环境的影响下采取若干措施,进行道路改线,可以满足交通便利、通行安全和使用要求,相关的工程经验可供类似项目参考和借鉴。
To the actuality of land resource shortage caused by the mountainous terrain in the Wenxi operation area of Lishui Port,this article studies the relationship between the port road transportation and the rear expressway,the method of connecting the port road to the 330 National Highway,and how all relevant parties along the port road can access it.A construction idea is proposed to extend the depth of the land area through the realignment of provincial roads.After the realignment,a combination of blasting excavation and mechanical excavation is used for deep excavation of road cuttings to reduce the impact of port clearance roads on highways.Interconnections are established within tunnels to connect with national highways,and road elevation design is based on the access elevations of all parties along the route.By taking several measures under the influence of complex surrounding environments,road realignment can meet the requirements of convenient transportation,safe passage,and usage.Relevant engineering experience can be used as a reference and inspiration for similar projects.
