摘要:以龙山县2015年棚户区改造及公租房建设项目为实际案例，研究BIM技术在高层房建施工中的应用。首先明确各分部工程量大、钢材成本控制、钻孔灌注桩溶洞处理等施工难点，搭建三维立体模型，生成场景动画，提高可视化效果。然后在项目施工过程中，通过BIM技术三维表现、专业深化与设计综合、方案模拟优化、工程量统计、三控三管、钢筋精细化管理、实施监管等措施解决传统工程在施工管理过程中存在的粗放式、经验式管理弊端，实现项目管理数据信息化、精细化、可视化、及危险可预见性的管理方式，大大提高管理创新理念及生产效率。最后针对施工难点提出相应的解决措施，模拟施工部署及进度、创新工法，深化设计碰撞检查、钢筋精细化施工、平台管控的施工全过程控制，便于技术交底、方案筛选与施工准备，进一步完善BIM的研究与应用力度。

Abstract: Taking the shantytown reconstruction and public rental housing construction project of Longshan County in 2015 as an actual case, this paper studies the application of the BIM technology in the construction of high-rise buildings. Clarifying that the construction difficulties includes large quantities of divisional works, strict cost control of steel, difficult treatment of karst cave of bored cast-in-place pile, and etc., a 3D model is built to generate scene animation and to improve the visualization effect. During the process of project construction, BIM-based measures are taken to solve the shortcomings of extensive and experiential management in the process of construction management of traditional projects, including the 3D visualization, professional deepening design and design synthesis, scheme simulation and optimization, engineering quantity statistics, three control and three management, refined management of reinforcement, supervision, and etc. The project management data then realizes informatization, refinement, visualization, and risk predictability management mode, greatly improving the management innovation concept and production efficiency. At last, in response to the construction difficulties, the corresponding solutions are proposed to simulate the construction deployment and progress, and to innovate the construction method, as well as to deepen the whole process control of design collision inspection, reinforcement refinement construction and platform control, which facilitates the technical disclosure, scheme selection and construction preparation, and further improves the research and application of BIM.
