摘要
以高沁高速跨S227中桥为工程案例,根据建设项目的具体情况,对连续箱梁门洞式支架法施工方案作了介绍,进而对工字钢的强度与刚度、钢管的强度与稳定性及基础的强度进行了验算,以确保工程质量。
Taking the Gaoqin highway across S227 mid-bridge as the engineering example, according to the specific situation of construction project, this paper introduced the construction scheme of continuous box girder door opening support method, then checked the strength and stiffness of H-section steel, the strength and stability of steel pipe and the strength of foundation, so as to ensure the engineering quality.
