高速公路桥梁施工对地表水水质影响的分析

The Analysis of Expressway Bridge Construction Influencing on Surface Water

以晋侯高速公路关门至侯马段施工期地表水环境监测为基础,根据桥梁工程施工进度,分析了各监测因子随工程进度而变化的规律,得出公路桥梁施工对跨越河流水质的影响具有阶段性,污染主要集中在桥梁基础施工和桥面施工阶段,建议加强此阶段地表水监测,并探讨适宜的监测频率。

Based on the monitoring of surface water during the construction of Guanmen-Houma expressway, according to phase of bridge engineering, the paper analyzed the monitoring factor with its rule of variation, discussed the construction of bridges across the fiver with the impact of stage, pollution that mainly concentrated in the basic bridge construction and bridge construction stage.Meanwhile,proposed to strengthen montoring in the stage of surface water and proposed appropriate monitoring frequency.
