摘要
支架作为工程常用的支撑结构,在桥梁工程中得到了广泛地应用.以黑山南北高速公路项目各种支架在桥梁中的应用为实例,着重论述传统式满堂支架、钢管桩支架、DOKA支架、少支点支架等4种支架形式的平面布置方案以及受力状态下的杆件变形和对基础的承载力要求,并据此给出各种支架方式的优缺点及适用情形,以便为后续项目提供参考.
Abstract
Bracket,as a common support structure in projects,has been widely used in bridge engineering.This paper takes the application of various brackets in bridges of Smokovac-Matesevo Section of Montenegro's Bar-Boljare Highway Project as an example,focusing on the plan layout scheme,deformation of rods under stress state and bearing capacity requirement of foundation of four bracing forms,namely,traditional full-tower bracing,steel pipe pile bracing,DOKA bracing,and less pivot bracing,and the advantages and disadvantages of various bracing modes as well as the applicable situations are accordingly given,so as to provide reference for the subsequent projects.
