Environment Monitoring And Assessment Of Highway Bridge In Construction Phase

Bridge construction has different influence on environment during different phase,including society,environment,acoustic and water.Large-scale bridge involves the wide range,more difficulties and short-time construction period,which has an irreversible effect on environment.It is the key technology to protect the ecology environment and monitoring during bridge construction,which responses the target of “green transportation”.However,the ecological protection and monitoring management of large-scale bridge construction was studied relatively less.This paper aimed at researching the ecological problem during large-scale bridge construction from the perspective of idea,management,monitoring and mitigation measures.Based on the relative research at home and abroad,the paper illuminnated the connotation of eco-friendly project from three levels(macroscopic,medium,microcosmic).The progress of bridge eco-effect was analyzed and classified into four different types.Then,the anlysis scope of bridge construction was identified.On the other hand,environmental monitoring factors were screened out through analyzing environmental impact identification matrix and the monitoring method and measure of different factors were put forward according to the characteristic of bridge project.The evaluation index system of environmental impact during bridge construction was developed and the quantified method and standards were come up with.Finally,the environmental impact of Wusu bridge was monitored and evaluated.The results indicated the monitoring index was good,which accounted for the different mitigation measures during bridge construction.This paper studied the environmental impact of bridge construction from idea,management,monitoring method and index,which prodives the reference for protecting ecological environment and building eco-friendly bridge.
