Environmental Hydrochemical Characteristics of a Dam Site of a Hydropower Station and its Influence on the Project

Environmental water’s corrosion evaluation of concrete (structure), steel bars and steel structures in reinforced concrete structures is an item of engineering investigation. Therefore, environmental water samples are used for water chemical composition testing during the investigation and carried out according to regulations. Evaluation is very necessary. Taking the Lai Hydropower Station dam site as an example, through the test results of the chemical composition of the water samples, the environmental water and engineering-related chemical characteristics are analyzed, and the corresponding corrosiveness evaluation is carried out according to the requirements of relevant standards, and the surface water and groundwater concrete (structure) is corrosive, indicating the degree of influence on the project. This paper also provide a basis for the project to take protective measures and put forward protecting measures recommendations.
