Abstract

Abstract: Upper and lower edge stress，horizontal and vertical displacement of different section length of the actual continuous beam bridge project rotation section are calculated and analyzed with finite element model． It was found that different section length has little effect on the stress of the rotation section，but has significant impact on displacement

Key words: continuous beam bridge, rotary method, construction of cast-in-place, section length, stress, displacement

摘要： 针对工程实例建立有限元分析模型，研究了不同分段长度对平转连续梁转体段受力的影响，分析了不同分段长度时转体段各截面上、下缘应力以及各节点累计水平和竖向位移。结果表明: 不同分段长度方案对转体段的应力影响较小，但对位移有着显著影响。
