摘要: 按照6种不同分跨的设计方案,每种方案又按照施工阶段采取几种不同预压荷载的计算比较来研究按照预压合龙施工工艺完成体系转换的预应力连续加劲梁吊拉组合体系桥的主梁结构性能,并选择体系的最优分跨比.

关键词: 吊拉组合桥, 预应力连续加劲梁, 分跨比

Abstract: The functional discontinuity of the C. C. S. B (Combined Cable-stayed Suspension Bridge) beam is a main hindrance to C. C. S. B's application.Whether the prestress technology is effective or not, and by this technology the beam's function is continuous or not is a key question.The paper pays close attention to the research of many bridges' characteristics, and each bridge's analysis is made by four states.Finally, it gives a study about C. C. S. B's span's division.

Key words: Prestress, continuous beam, combined cable-stayed suspension bridge (C. C. S. B), span division
