天津滨海新区港塘路改造工程设计关键问题研究
发布时间：2018-12-06 19:29
【摘要】：滨海新区作为天津经济发展的增长极，为确保其持续快速发展，，必须完善市政基础设施建设。港塘路改造可以更好地加强滨海新区的两大主要城区—大港区和塘沽区快速联系，因此港塘路改造工程的建设势在必行。 本文基于天津市滨海新区2005-2020年总体规划和港塘路规划，通过对2030年港塘路交通量进行预测和服务水平分析，以及考虑周边地块的开发建设时序安排、土地规划性质等因素，确定了近期实施横断面布置为双向六车道、非机动车道和人行道暂不实施的横断面设计方案；充分调研道路网及周边建筑物等现状，通过方案分析比较，确定了经济合理的平面方案和节点立交方案；通过对既有路的破损调查，并根据弯沉检测结果，在计算分析的基础上了确定了路面结构补强厚度为36cm，并制定了旧路补强方案和相应的施工措施；通过4个方案的技术经济比选，最终确定取土坑路段采用加筋土换填和挡土墙方案，并通过沉降观测结果验证了方案的可行性。
[Abstract]:Binhai New area is the growth pole of Tianjin's economic development. In order to ensure its sustainable and rapid development, it is necessary to perfect municipal infrastructure construction. The reconstruction of Gangtang Road can better strengthen the rapid connection between Dagang District and Tanggu District, the two main urban areas of Binhai New area, so the construction of Gangtang Road Reconstruction Project is imperative. Based on the overall plan of Tianjin Binhai New area 2005-2020 and the planning of Port Tanglu, this paper analyzes the traffic volume and service level of Port Tanglu in 2030, and takes into account the timing of development and construction of surrounding plots, the nature of land planning, and so on. The cross section design scheme which is arranged as six lanes in two directions and not implemented in non-motorized lanes and sidewalks in the near future is determined. Through the analysis and comparison of the road network and the surrounding buildings, the economic and reasonable plan and the node interchange scheme are determined. Based on the investigation of the damage of the existing road and the results of deflection detection, the reinforcement thickness of the pavement structure is determined to be 36 cm on the basis of calculation and analysis, and the reinforcement scheme of the old road and the corresponding construction measures are worked out. Through the technical and economic comparison of the four schemes, the scheme of reinforced earth replacement and retaining wall is determined and the feasibility of the scheme is verified by the settlement observation results.
