摘　　要：建筑工业化的基本特征是在建筑行业内以机器生产构件和产品代替人工生产,以机械施工替代人工施工,其衡量标准是机器生产代替人工的比重。建筑工业化率表示在整个建筑生产过程中,以工业化的机械生产代替人工手工劳作的比例,并通过该比例展示出整个建筑产业链的工业化水平。本文提出了权重系数法建筑工业化率计算模型,以南京市某地下工程为例,确定了新型工业化建造模式权重系数β取值(0.4,0.25,0.15,0.09),计算得出应用装配式组合钢筋技术系统的工业化率约为31%。该评价指标有利于系统评估建筑工业化整体水平,为江苏省装配式建筑乃至其他省份地区出台装配式评价标准提供参考。As the country vigorously promotes the industrialization of new buildings and the sustainable development of assembled buildings,the Ministry of Housing and Urban-Rural Development released the Standard for Assessment of Prefabricated Building(GB/T51129-2017),in which the prefabrication ratio,as an important indicator in the evaluation system of assembled buildings,has become the main basis for governments at all levels to formulate policies related to assembled buildings.Compared with the local documents related to the calculation of the prefabrication ratio issued by each region in China,it can be seen that the details of the terms are slightly different,but they are all based on the national standard and supplemented and improved according to the local industry chain development characteristics.In the specific engineering application,it can be seen that,first of all,the application ratio of prefabricated components in assembled buildings is already high,but the production method and construction and building organization of domestic factories are still relatively backward,and prefabricated components are carried out on-site in accordance with the traditional manual mode of mold support and post-pouring during on-site construction,which does not give full play to the advantages of assembled buildings in terms of construction.This implementation is a kind of enhancement for the value of the prefabrication ratio,but essentially it does not achieve the effect of replacing manual work with mechanical work,and even consumes more labor in the whole construction process.Secondly,due to different evaluation standards,there are differences in the calculation methods and results of both the assembly rate and prefabrication rate.In addition,the traditional building assembly thinking in the industry mostly equates the process of promoting the industrialization of construction with increasing the prefabrication and assembly rate of component factories,and simply using the assembly rate or prefabrication rate as the evaluati
