摘　　要：传统震后建筑进度BIM估计模型,未考虑精益管理对建筑施工的影响,造成建筑成本浪费较多,影响后期建筑施工进度。本文构建基于BIM和精益管理的震后建筑进度评估模型,根据模型细分震后建筑进度评估过程,在此基础上根据BIM实施三维算量,采用进度计划编制子模型获取各分项工程量,确定建筑施工的主要进度计划,实现对建筑进度计划的编制;通过虚拟施工和现实施工两条主线,利用进度控制子模型实现对施工状态的模拟和精益管理。以此为基础,进行挣值分析比较计划施工成本、实际施工成本和挣值曲线,获取震后建筑的施工进度与成本情况。实验结果说明,本文构建的模型可对震后建筑进度和工程成本进行精准估计,能够减少成本浪费。The traditional BIM estimation model of post-earthquake construction schedules ignores the effect of lean management on the construction schedule,thus wasting construction costs and affecting the later stages of the construction schedule.In this work,an evaluation model of post-earthquake construction schedule is constructed on the basis of BIM and lean management.In the proposed model,the evaluation of post-earthquake building schedule is subdivided.Then,three-dimensional calculation is implemented on the basis of BIM,and the submodel of schedule planning is used to obtain subproject quantities.The main schedule plan of building construction is determined,and the construction schedule plan is established.Construction state is simulated and refined by using the schedule control submodel in virtual and practical construction.On the basis of simulation and practical results,the planning construction cost,actual construction cost,and earned value curve of the post-earthquake construction project are analyzed and compared,and the construction schedule and cost of the project are obtained.Experimental results show that the proposed model can accurately estimate the schedule and costs of post-earthquake construction projects.
