甘肃（天水）国际陆港见善路交叉节点技术方案调整的实践与思考

Practice and Reflection on Technical Scheme Adjustment of Jianshan Road Intersection Node in Gansu (Tianshui) International Land Port

摘要:

目前城市基础设施项目面临越来越多的动态挑战，运用“动态治理”的系统性思维是解决问题的关键。以甘肃（天水）国际陆港见善路与麦甘公路交叉节点为研究对象，梳理了该节点由于区域路网规划的重构、立交结构型式的多维度比选、投资模式的变化引起技术方案调整的全过程，研究总结了该节点技术方案调整过程中的实践经验：技术方案调整的本质是在动态环境中寻求功能、经济与社会价值的多维统一，应在项目策划及立项阶段把好关口，也应以更加开放、灵活、系统的态度，将每一次调整都视为优化项目、创造价值的机遇。研究成果可为新时代背景下重大工程项目的科学决策与可持续实施提供借鉴。

Abstract:

At present, urban infrastructure projects are confronted with an increasing number of dynamic challenges. Applying the systematic thinking of "dynamic governance" is the key to solving these problems. Taking the intersection node of Jianshan Road and Maigan Highway in Gansu (Tianshui) International Land Port as the research object, the entire process of technical scheme adjustment at this node caused by the reconstruction of regional road network planning, multi-dimensional comparison and selection of interchange structure types, and changes in investment models is sorted out. The practical experience in the process of adjusting the technical scheme of this node is studied and summarized. The essence of adjusting technical schemes lies in seeking a multi-dimensional unity of functional, economic and social values in a dynamic environment. It is necessary to strictly control the project planning and initiation stages, and also adopt a more open, flexible and systematic attitude, viewing each adjustment as an opportunity to optimize the project and create value. The research results can provide references for the scientific decision-making and sustainable implementation of major engineering projects in the context of the new era.
