(同濟大學(xué)建筑設(shè)計研究院，上海 200092)［摘要］采用多塔懸索橋撓度理論，對三塔懸索橋的矢跨比、主塔剛度、加勁梁高度和主塔高差等進行了參數(shù)分析。通過這些分析，有利于幫助人們把握三塔懸索橋的受力特點，得出的結(jié)論可供類似橋梁方案設(shè)計時參考。［關(guān)鍵詞］三塔懸索橋；撓度理論；參數(shù)分析Parameter Analysis of 3-tower Suspension Bridges Using Deflection TheoryLuo Xiheng(Architectural Design & Research Institute of Tongji University，Shanghai 200092,China)
Abstract:Using the deflection theory of suspension bridges with multi-tower,parameter analysis has been performed on rise-span ratio,stiffness of main tower,depth of stiffening girder and high difference between towers. Those analysis works are useful for the understanding of structural characteristics of 3-tower suspension bridges,and the conclusions drawn can be referred in scheme design stage of similar bridges.Keywords:suspension bridge with 3-tower；deflection theory；parameter analysis作者簡介：羅喜恒(1969-)，男，高級工程師。參考文獻［1］羅喜恒,韓大章,萬田保. 多塔懸索橋撓度理論及其程序?qū)崿F(xiàn)［J］.橋梁建設(shè),2008(2):41-44.［2］泰州長江公路大橋設(shè)計項目組. 泰州長江公路大橋三塔兩跨懸索橋結(jié)構(gòu)分析研究［R］. 南京: 泰州長江公路大橋設(shè)計項目組，2007.
