基于BIM的装配式建筑施工场地布置及优化技术

Layout and optimization technology of prefabricated building construction site based on BIM

以装配式建筑施工场地布置为研究对象,结合绿色施工理念,利用参数化建模方法构建了装配式建筑施工场地布置BIM模型。根据装配式建筑施工现场所要满足的具体要求,在考虑采用再生混凝土骨料的基础上,充分利用BIM模型的特点,将装配式建筑施工场地布置的约束限制条件和影响因素转化为可量化的数据,并构建了多目标函数,利用遗传算法求解,得到了不同的布置方案。然后根据所求得的结果,采用模糊筛选方法进行了方案比选,最终确定了装配式建筑施工场地布置的最佳方案。

Taking the layout of prefabricated building construction site as the research object,combining with the concept of green construction,the BIM model of the layout of prefabricated building construction site was constructed by adopting the parametric modeling method.On the basis of considering the use of recycled concrete aggregate,according to the specific requirements to be met by the layout of prefabricated building construction site,the constraint conditions and influencing factors of prefabricated building construction site were converted into quantifiable data by making full use of the characteristics of BIM model.The multi-objective function was constructed and solved by genetic algorithm,and different layout schemes are obtained.According to the results obtained,the fuzzy selection method was used to compare the schemes,and the optimal layout scheme of the prefabricated building construction site was finally determined.
