铁路绿色建筑施工污染控制分析与研究

Pollution Control in Railway Green Building Construction

铁路在传统建筑施工过程中施工现场的污染指数偏高,影响地区生态环境。为此利用工厂预制铁路绿色建筑,实现对施工现场的零污染控制。该方法根据城市气候等因素的不同,量化分析铁路建设区域的环境概况;明确铁路进站场地高架式、线侧式的空间特点,设计符合实际工况的建筑空间结构预制架;结合欧式距离法的基本理论与白化权函数,以建立的评价模型测算预制架的污染程度;设置建筑安放位置,装配铁路建筑预制架,并计算施工现场污染率,实现对施工场地的零污染控制。

The traditional railway construction process resulted in the high pollution index of the construction site and affecting the regional ecological environment.The factory prefabricated railway green building is used to realize zero pollution control on the construction site.According to the difference of urban climate and other factors,this method quantitatively analyzes the environmental situation of railway construction area.It defines the space characteristics of the railway entrance site in the form of viaduct and line side,and design the prefabricated building space structure in line with the actual working conditions.Combining with the basic theory of euclidean distance method and whitening weight function,the evaluation model was established to calculate the pollution degree of prefabricated frame.The study sets up the location of the building,assemble the railway prefabricated frame,and calculate the pollution rate of the construction site,so as to realize the zero pollution control of the construction site.
