漕河渡槽结构型式选择和论证

Selection and demonstration for structure of Caohe River Aqueduct

结合漕河渡槽现场地形地质条件,论述了板梁式结构和拱式结构等各种型式采用的可能性及优缺点.通过多种结构方案的具体工程布置、大量的工程量计算和技术经济综合比较,推荐采用20m跨(旱渡槽段)和30m跨(主河槽段)单联3槽多侧墙结构方案.

In accordance with the topographic and geologic condition of Caohe River Aqueduct, the feasibility and both the advantage and disadvantage of various types including the slab-gird structure and the arch structure for the aqueduct are discussed herein. The design alternative plan of the approach sections (on both the banks)of the aqueduct with the spans of 30m and the main section (across the main channel)of the aqueduct with the structure of single connection of three flumes with multi-side walls is recommended based on the comprehensive comparison made on various project layouts, an amount of calculations on the construction amount and the relevant technical and economic comparison as well.
