南水北调中线工程大型渡槽槽身支撑架方案设计与安全分析

The Middle Route of South-to-Nouth Water Transfer Project with supporting frame design and safety analysis for large aqueduct

南水北调中线干线工程在石家庄以南分布有20多座渡槽,槽身支承结构施工方案的制定和实施,是整个渡槽工程施工的核心技术,渡槽上部结构施工过程的稳定问题对工程质量和安全产生巨大的影响。也是槽身施工的重点和工作量最大的工作。其方案必须安全可靠、经济实用,需要根据实际地质情况和上部结构详细进行分析研究确定。本文以泜河渡槽为例进行了叙述。

There are more than 20 aqueducts of the Central Line Project of South-to-North Water Diversion distributed in the south of Shijiazhuang.How to formulate and implement the construction scheme of the aqueduct body supporting structure is the core technology of the whole aqueduct project construction.The stability of the upper structure construction process of the aqueduct has a great impact on the quality of the project and the safety.And it is also the key point of construction of the aqueduct body,which needs a lot of work.The scheme of the aqueduct body supporting structure must be safe and reliable,economical and practical and determined according to the practical geological conditions and the upper structure.This thesis gives a full account of the Zhi River aqueduct.
