摘要
对已建输水渡槽工程结构与跨度以及南水北调中线大流量预应力渡槽工程本身的特点进行分析的基础上,研究沙河梁式渡槽上部结构型式、受力体系、槽数与跨度,并结合满堂架、造槽机、架槽机施工方法,对不同结构与跨度方案的优缺点从结构受力、过流条件、防洪影响、施工技术水平与施工质量、施工工期、经济性、安全性等多方面进行综合对比,论证沙河渡槽经济合理的上部结构型式与跨度。
Based on analyzing of the structural type and span of the aqueducts built and precast concrete structures of the aqueducts characterized by low head and high flow in the South-to-North Water Diversion Project,the author conducted a comprehensive comparison for the schemes of different structure and span in aspects of structure stress, over-current condition, flood control, construction technology and control, time limit, safety and economics and combined with study on the structural type, the applied force system, the number of grooves and the span and demonstrated the rationally economical upper structural type and span.
