浅谈Revit及Navisworks在连续梁钢筋优化中的应用

Application of Revit and Navisworks in reinforcement optimization of continuous beam

在当前的社会形势下,预应力连续梁桥数量在国内已经逐步增加,其对桥梁结构设计的要求越来越高。桥梁连续梁内部结构钢筋及预应力钢筋错综复杂,在施工过程中二者容易出现空间位置冲突的现象,从而增加施工难度,甚至影响桥梁结构原设计应力状态。为解决这一难题,以某项目连续梁桥BIM技术应用为研究对象,通过使用BIM技术将整个连续梁进行精确还原,建立整个连续梁模型,对结构钢筋与预应力钢束之间的碰撞进行检查,出具详细的碰撞报告、钢筋优化报告以及多孔振捣通道设计方案,在不影响主体结构受力的情况下,对结构钢筋、预应力钢筋给予适当的调整,保证连续梁结构受力安全及混凝土浇筑质量。BIM建模技术在连续梁钢筋优化中的应用,避免了钢筋的碰撞,解决了钢筋布置过于密集而影响混凝土振捣,继而产生空洞、脱空、麻面等混凝土病害的技术难题。

Under the current social situation,the number of prestressed continuous beam bridges has been increasing gradually in China,and the requirements for their structural design are getting higher and higher.Because of the complexity of the reinforcement and the prestressed reinforcement in the continuous beam of bridges,it is easy to have the conflict of spatial position between the two in the process of construction,which will increase the difficulty of construction and even affect the original design stress state of the bridge structure.To solve this problem,the application of BIM technology to the continuous beams is taken as a topic,by using it the whole continuous beam is restored accurately,the continuous beam model is established,the collision between structural reinforcement and prestressed steel bundles is checked,a detailed collision report,reinforcement optimization collision and porous vibrating channel design are issued,and in the case of not affecting the structure stress of the main body,the structural reinforcement and prestressed steel are appropriately adjusted to ensure the safety of continuous beam structure and concrete pouring quality.After the application of BIM modeling technology in reinforcement optimization of continuous beam,the collision of reinforcement is avoided,and the following technical problems are solved,such as the dense reinforcement placement impacting concrete vibration,followed by hollow,escapes,pits and other concrete diseases.
