摘要: 为解决装配式建筑吊装施工空间冲突问题,以装配式建筑吊装施工空间冲突为研究对象,提出装配式建筑吊装施工的5类对象空间及单个对象的3类空间,总结施工作业的3大类空间冲突类型,提出空间冲突严重性的量化评价指标;依据装配式建筑的施工特点,建立各类对象的三维空间占用模型和时空占用模型,提出吊装作业空间冲突检测方法,构建以最小吊装工期、最低机械租赁成本、最低施工成本及最小空间冲突为目标的吊装施工优化模型,并基于实际项目数据进行案例分析。结果表明:该模型及算法在装配式建筑吊装施工中可有效减少作业面冲突,降低机械租赁成本,优化施工进度计划,提高施工安全绩效。

Abstract: In order to solve space conflicts in prefabricated building hoisting construction, with the conflict as research object, five kinds of object space and three kinds of space for single object were presented, three space conflict types were summarized, and consequently, quantitative evaluation indexes for spatial conflict severity were proposed. Secondly, a 3D spatial occupancy model and spatio-temporal occupancy model for different objects were developed according to construction characteristics of prefabricated buildings. Then, space conflict detection algorithm was put forward, and an multi-objective optimization model was built that minimized hoisting period, rental cost of cranes, construction cost and space conflict, which was applied into an actual prefabricated building project. The results show that this model and algorithm can effectively reduce conflict of working space and rental cost of cranes, thus optimizing hoisting schedule and improving safety performance.

Key words: prefabricated building, space conflict, multi-objective optimization, hoisting construction, safety performance
