一种快速建模技术在现场施工中的应用研究

摘要

随着国家建筑业政策的陆续出台,BIM技术在各工程建设项目中都开始了广泛的应用,其价值主要表现在:三维渲染快速展示、快速算量精确提升、碰撞检查减少返工等方面,但在三维渲染快速展示方面,由于BIM技术的基础是工程建筑物的属性数据,对于中间建造环节部分的实景展示,目前的BIM主流软件都无能为力,只能是虚拟演示,现实感差,这对于BIM技术在现场的交流展示及技术交底等工作都带来了较大的影响.结合铁路桥梁施工案例,对施工阶段现场进行快速实景建模分析,并得出了一些有益结论.%With the introduction of national construction policies,BIM technology has been widely used in various project construction projects.Its value is mainly reflected in three-dimensional rendering and rapid display,including rapid calculation and accurate increase,collision check and reduce rework,etc.Because the basis of BIM technology is the attribute data of engineering buildings,the current BIM mainstream software is powerless for the actual display of the intermediate construction segment in terms of 3d rendering.It can only be a virtual demonstration.The reality is poor.It will have a great impact on the communication and technical disclosure of BIM technology in the field.In this paper,we come to get some useful conclusions on the construction of railway bridge construction.In this paper,it makes a research and analysis on the quick live modeling construction application.
