钢栈桥综合加固技术研究

Study on Comprehensive Reinforcement Technology of Steel Trestle

钢栈桥一般采用钢管桩基础、贝雷梁为主承重梁的结构,因其施工速度快、安装拆除方便、可重复使用等优点,在桥梁、港口、大坝等基础设施工程中得到广泛应用。当桥梁基础受到水流、浪、浅覆盖层等不良地质环境条件的影响时,桥梁基础的稳定性以及承载性能都面临一定的挑战。以某临时钢栈桥工程为研究背景,对其结构进行加固处理,阐述了加固的设计计算方法,并确定了加固施工方案。

Steel trestle bridges are generally constructed with steel pipe pile foundations and Bailey beams as main load-bearing beams.Due to their advantages of fast construction speed,convenient installation and removal,and reusability,they are widely used in infrastructure projects such as bridges,ports,and dams.When the bridge foundation is affected by adverse geological environmental conditions such as water flow,waves,and shallow overburden,the stability and bearing capacity of the bridge foundation face certain challenges.Taking a temporary steel trestle bridge project as the research background,the structure was reinforced,the design and calculation methods of reinforcement were elaborated,and the reinforcement construction scheme was determined.
