公路施工期对空气环境影响的研究

公路施工阶段常有粉尘、烟气等污染物产生,给当地居民带来不便,造成农作物减产,经常引起经济纠纷,甚至发生阻挡施工的现象.通过对国道211线（宁夏境）古窑子至青铜峡段高速公路施工过程中粉尘、烟气的监测和试验,取得了环境的现状数据,分析了公路建设过程中主要大气污染物的种类及危害性.为减少施工过程对周围空气的污染,提出了针对性的防治措施,既有效保护了施工人员身体健康和当地空气环境,也维护了群众的利益.

Air environmental impact during highway construction

The dust,flue gas and other pollutants are often generated during the highway construction.These bring lots of inconvenience to the local residents,result in crop failures,and often cause economic disputes,or the construction is even stopped.Through monitoring and testing of the dust and flue gas during the construction of Guyaozi to Qingtongxia highway in National Highway 211(Ningxia border),the types and hazards of the main atmospheric pollutants during the highway construction are analyzed on the present data of environment.For reducing air pollution from construction process,countermeasures are put forward to safeguard the worker healthy in construction,local air environment and interests of the masses effectively.
