Analysis of Hydrochemical Characteristics and its Influences on Jiaodong Water Diversion Project

Abstract

The water chemistry characteristics along the Jiaodong water transfer line and its impact analysis play an important role in supporting water quality safety and operation management. In this paper, the water chemistry characteristics along the Jiaodong water transfer project were studied, and the water chemistry characteristics and their influencing factors in the study area were analyzed by using Piper's trilinear diagram, Gibbs diagram and SPSS26 statistical analysis software for correlation. The results show that the surface water and groundwater along the Jiaodong water transfer project are both weakly alkaline, and the chemical type of groundwater in the traversing area is Na Ca-HCO-3 water, while the chemical type of surface water is Na Ca- HCO-3 water. The groundwater in the crossing area of Jiu Dong water transfer project is mainly controlled by rock weathering and evaporation concentration, and the water chemistry type of groundwater in different areas shows certain differences; the correlation between the channel water and groundwater and surface water along the route is weak in water quality, and surface water and groundwater basically have no influence on the water quality of channel water transfer during the normal water transfer period; the groundwater quality along the route basically has no corrosive influence on concrete, and the groundwater quality has no corrosive influence on Groundwater quality has no corrosive effect on concrete, but groundwater quality has some influence on reinforcement and steel structure in concrete.
