摘要:礼嘉嘉陵江特大桥为国内首座上承式梁拱组合刚构桥,具有结构设计新颖、施工工艺复杂、地质环境特殊的特点。施工过程中通过建立高精度BIM模型(LOD400),运用重合分析、三维碰撞检查、可视化交底等BIM技术辅助开展方案评审及交底,提高桥梁的可建造性。通过BIM技术+项目管理(PM)+物联网集成应用建立BIM管理协同平台,利用移动终端和物联网技术实时采集数据的功能,实现PC端和移动端协同应用,开展进度、质量、安全方面管控,提升项目精细化管控水平。自主研发基于视频流的智能图像自动学习(AI)识别系统,自动识别人员与安全帽佩戴、安全背心佩戴等行为,对现场监督(安全行为)提供有力保障。通过BIM技术探索及应用有效推广了桥梁工程BIM技术应用实践经验。
Abstract: Lijia Jialing River Bridge is the first beam camber deck bridge in China, which has the novelty in structural design, the complexity in construction and the complication in geological environment. During the construction process, high level BIM model (LOD 400) is developed. BIM technologies have been implemented, for example, integrated analysis, 3D clash detection and visualization helps the review and delivery process to improve the constructability of the bridge. BIM collaborative management platform can be established through integrating BIM, Project Management (PM) and integrated implementation of Internet of Things (IoT). It can uses the mobile terminal and IoT to enable live-time data collection, thus to achieve the collaborative operation between PC and mobile terminal to process the management in schedule, quality and safety, therefore, the performance of Lean Management can be improved. Artificial Intelligence (AI) smart image recognition system based on video streaming has been developed independently to enable the automatic detection of the person if wears helmet and safety vest, thus provides a strong construction supervision in safeties. It has effectively promoted the experience of practical BIM technologies through the exploration and the implementation of BIM technologies in bridge engineering.
