悬臂浇注法作为拱桥施工过程中的一种新型施工工艺,克服了不利地形的缺陷,也可以将拱桥作为斜拉桥和连续刚架桥分段施工,具有投资较少,施工方便,整体结构性好,后期维护少,维修保养方便等优点。本文结合具体实际工程,采用桥梁专业有限元软件MIDAS/Civil建立了有限元模型,给出了预期的控制目标状态的桥梁位移和内力;探讨拱圈合龙方法及成桥后索力拆除等问题,希望能对类似工程提供经验借鉴。
As a new type of construction technology in the process of arch bridge construction, cantilever casting method overcomes the disadvantages of unfavorable terrain, and can also be used as a cable-stayed bridge and continuous rigid-frame bridge to construct the sections with less investment, convenient construction and overall structural Good, less maintenance, easy maintenance and other advantages. In this paper, the finite element model is established by using the bridge professional finite element software MIDAS / Civil, and the expected displacement and internal forces of the bridge are obtained. In addition, Hope to provide similar experience to learn from.
