文章对与南水北调中线干线工程交叉的工程进行了分类,并对不同穿越跨越型式的选择影响因素加以分析,提出在进行交叉方案比选时,应针对南水北调中线干线工程不同的建设运行阶段、总干渠的结构断面、地质情况和建筑物的类别、投资和后期的运行管理进行综合分析,合理选择。对穿越跨越南水北调中线干线工程安全措施从设计和施工等方面进行了分析论述,为类似交叉工程的设计、施工提供了一定的借鉴参考价值。
The paper classifies the projects which cross the South-to-North Water Diversion Middle Route Project and analyzes the influencing factors of different crossover type choices. In the process of comparison and selection of cross-over plans, it is necessary to focus on the different construction and operation phases of the Middle Route of South-to-North Water Diversion Project, The structural section, geological conditions and types of buildings, investment and post-operational management of a comprehensive analysis, a reasonable choice. This paper analyzes and discusses the safety measures of the main line across the midline of South-to-North Water Diversion, and provides some references for the design and construction of similar cross-engineering.
