大跨度斜拉桥的施工监控研究

Study on the Construction Control of Long-span Cable-stayed Bridge

本文以四川省绵阳市一号桥为依托,根据施工图设计文件,在对该桥进行有限元仿真模拟的基础上,研究了大跨度斜拉桥的施工控制内容与方法,通过理论计算与实际测量相比较证明了本文施工控制方法的科学性。该方法不仅为绵阳一号桥的顺利施工与结构安全提供了技术支持,也为以后同类型斜拉桥的施工控制提供了技术参考。

This paper takes Mianyang City No. 1 Bridge as the basis, according to the construction drawings and design documents,on basis of finite element simulation on the bridge,research content and method of the construction control of long-span cable- stayed bridge,through theoretical calculation and actual measurement comparison shows that this construction scientific control method. This method not only is Mianyang No. 1Bridge of the smooth construction and the structure safety provides technical support,also provide technical reference to the construction control of cable- stayed bridge after the same type.
