Abstract


Water Environment impact study yes ranging from preventive the Environmental Protection the goal departure , the use of appropriate evaluation methods and research means , determine the construction project emissions 's major pollutants pairs of water environment the possible impact scope and extent of , put forward environmental Protection Countermeasures in and measures to , from the protection an environmental perspective for the construction project scheme optimization provide the basis for . In the tunnel construction process, due to engineering operation , making the the loss of groundwater process often carry large amounts of construction wastewater , to enter the surface water body . In addition, because engineering perturbation , causing geological environment middle groundwater occur change, and usually causes surface water body and the groundwater systems occurrence of hydraulic connection . Analysis and evaluation of railway tunnel on water environment effects, thereby from the water changes in environmental quality angle put forward engineering control measures , right practical engineering has a certain guiding significance. This article in order to Yuhuai Railway Geleshan tunnel for example, analysis engineering construction on water environment impact of the problem . Geleshan tunnel construction water environment problem is mainly include the surface water environment and the groundwater environmental two aspects of . Against the Geleshan tunnel construction characteristics , through on-site investigation and sources of pollution analysis to determine the environmental monitoring and evaluation factor , and to take gather information, the wild reconnaissance , field monitoring , Indoor experiment, data analysis of the combination the technical route carry out the construction process Water environmental impact studies . Thesis in order to tunnel drainage of surface affected by satisfied that the water body as the research priorities, the use of comprehensive index method and fuzzy comprehensive evaluation Legalist carry out water environment quality analysis, same time, the monitoring the of tunnel construction on groundwater water level and water quality the impact of . Results showed that the , the tunnel construction process in the short term within the pairs of ground surface affected by satisfied that the water body the water quality have a certain influence , but with the construction methods 's improvements, water quality gradually restored to a normal level ; tunnel construction did not make groundwater level happen decline in , water quality did not worsen trend in . Research The results pairs of engineering construction put forward had a positive of the dynamic design and construction recommendations , effectively reduce the groundwater the wastage and surface water 's pollution, reach protect the ecological environment and water bodies safety purposes.
