摘　　要：为了制订合理的高层建筑CFG桩施工成本计划,实时监控成本,达到施工成本优化控制的目的,提出高层建筑CFG桩复合施工成本优化控制算法。该算法以BIM为基础,建立高层建筑CFG桩3D模型,集成CFG桩体施工的全部进度信息与成本信息,结合5D信息平台动态模拟出CFG施工过程,生成质量控制清单;依据上述生成结果以CFG桩施工工期最短以及CFG桩施工成本最低为施工成本优化控制目标函数,并设计该目标函数对应的约束条件;在得出的约束条件内,利用混合粒子群算法对目标函数进行求解,得到目标函数的最优解。试验结果表明:该方法能够构建高层建筑CFG桩的3D模型,并对项目施工各项成本与进度进行实时监控,控制后高层建筑CFG桩复合施工成本明显降低,同时缩短了整体施工进度,减少了资源浪费,降低了成本,提高了企业利润。In order to develop a reasonable cost plan for the construction of CFG piles in high-rise buildings,monitor costs in real time,and achieve the goal of optimizing and controlling construction costs,a composite construction cost optimization control algorithm for CFG piles in high-rise buildings was proposed.This algorithm was based on BIM and establishes a 3D model of high-rise building CFG piles.It integrated all progress and cost information of CFG pile construction,and dynamically simulates the CFG construction process using a 5D information platform to generate a quality control list.Based on the above generated results,the shortest construction period and lowest construction cost of CFG piles as the optimization control objective function was selected for construction cost,and design the corresponding constraint conditions for this objective function.Within the obtained constraints,the hybrid particle swarm algorithm was used to solve the objective function and obtain the optimal solution of the objective function.The experimental results show that this method can construct a 3D model of CFG piles in high-rise buildings and monitor various construction costs and schedules in real time.After controlling,the composite construction cost of CFG piles in high-rise buildings is significantly reduced,while shortening the overall construction schedule,reducing resource waste,lowering costs,and improving enterprise profits.
