摘要
以儒乐湖大桥为工程背景,介绍了该桥的设计方案比选与计算分析。该桥采用(25+40+50+3×60+50+40+25)m=410m连续梁拱组合式桥梁,采用midas Civil软件对其拱脚V撑进行模拟分析,得出有意义的结论。根据计算结果,该桥拱肋在设计荷载作用下具有足够的安全性,并具有一定承受超载的能力。
Taking Rule Lake Bridge as the engineering background, this paper introduces the comparison, calculation and analysis of design schemes for this bridge. This bridge is a 410-m (25 m+40 m+50 m+3× 60 m+50 m+40 m+25 m)-span continuous beam arch composite bridge. The MIDAS Civil software is used to simulate and analyze the V-support arch foot of this bridge. The significant conclusion is achieved. Based on the calculation result, the arch rib of this bridge has the sufficient security under the design load effect, and has a certain capacity of bearing the overload.
