基于BIM的装配式建筑并行施工作业空间冲突识别

为识别装配式建筑施工并行作业之间的空间冲突，分析装配式建筑施工项目现场各类作业空间占用需求，利用BIM技术模拟作业空间占用，引入混合轴向包围盒（AABB）与有向包围盒（OBB）算法，建立施工现场并行作业空间冲突检测模型。结果表明:所建立的模型可有效预测施工现场并行作业之间的空间冲突，为进一步的空间资源优化与项目安全管理提供支撑。

Conflict recognition on working space in concurrent construction of prefabricated building based on BIM

To identify the space conflict between the concurrent operations in the construction of prefabricated building,the occupancy requirements of various working spaces on the construction project site of prefabricated building were analyzed.The working space occupancy was simulated by using the building information modeling(BIM)technology,and a detection model for the space conflict of concurrent operations on the construction site was established by introducing into the axis-aligned bounding box(AABB)and orientational bounding box(OBB).The results showed that the proposed model could effectively predict the space conflict between the concurrent operations on the construction site,and it provides support for the further spatial resource optimization and project safety management.
