【摘要】 钢管混凝土结构在施工过程中会在钢管内产生初应力.本文综述了钢管混凝土柱的初应力问题和现有构件研究成果.在此基础上,分析了几座已修建的不同跨径及截面形式的钢管混凝土拱桥的初应力度的范围.同时对钢管混凝土拱桥的初应力问题进行了初步探讨,提出了钢管混凝土拱桥初应力问题的研究方向及建议.更多还原

【Abstract】 The steel tube of Concrete Filled Steel Tubular structure will produce initial stress while in the pro- cessing of construction.This paper reviews the initial stress problems of CFST architecture columns,and bases on the researching result of existing members,the paper also analyses the initial stress’ s degree about several existing kinds of different span and section-shape CFST arch bridges as well as preliminary analysis the initial stress problems of CFST arch bridge.In the end,the paper indicates some problems that need to be solving and presents its research current and advice about CFST arch bridge.更多还原
