复杂地形条件下高铁枢纽片区路网及场地竖向规划设计研究

Study on Vertical Planning and Design of Road Network and Site of High-speed Railway Hub Area under Complex Topographic Condition

摘要:

结合荆门高铁西站片区路网及场地竖向规划实例，分析复杂地形条件下高铁枢纽片区场地竖向规划设计的特点，提出竖向规划设计互反馈流程，从路网及场地竖向规划设计两个方面梳理了竖向控制因素要点、竖向分区、土方填挖要求及土方计算与调配方法。最后总结认为：复杂地形条件下，道路及场地竖向规划应综合考虑铁路、市政道路、地面排水防洪、用地性质、土石方平衡、城市景观和工程建设等方面的要求；道路及场地竖向规划设计应互为交叉反馈，满足土方总体平衡，工程建设经济合理，实现总体竖向规划设计方案的合理可行。

Abstract:

Combined with the vertical planning of road network and site of the high-speed railway west station area in Jingmen, the characteristics of vertical planning and design of high-speed railway hub area under complex topographic condition are analyzed. The reciprocal feedback flow of vertical planning and design is put forward. The vertical control factor essentials, vertical zoning, earthwork filling and exaction requirements, earthwork calculation and deploying method are sorted out from two aspects of the road network and site vertical planning and design. The conclusion shows that the comprehensive requirements of railway, municipal road, ground drainage flood control, land usage, earth-rock balance, urban landscape and engineering construction should be considered in the road and site vertical planning under the complex topographic condition. The reciprocal cross-feedback should be given to the vertical planning and design of road and site in order to meet the overall balance of earthwork, the economic and reasonable engineering construction, and to realize the reasonable feasibility of overall vertical planning and design scheme.
