张峰水库输水工程枢纽地下水对环境的腐蚀性评价与分析

Evaluation and Analysis of the Corrosivity of the Groundwater of the Key Project of Water Transmission of Zhangfeng Reservoir on the Environment

从离子浓度的大小可以判定地下水与地表水对混凝土、钢筋是否有腐蚀性,以便为材料的选择提供依据。对张峰水库输水工程枢纽部分的地下水样进行了腐蚀性分析测试,并就测试结果进行了评价,指出地下水对混凝土没有腐蚀性,对钢有弱腐蚀,选择钢筋时应考虑。

The ion concentration can be used to determine that weather or not the groundwater and the surface water have the corrosivity on the concrete and stee l bar and to provide the reference for the selection of the materials. This pape r makes the corrosivity analysis and test on the groundwater sample of the key p roject of water transmission of Zhangfeng Reservoir, and makes evaluation on the test results, and points out that the groundwater has no corrosivity on the con crete and has the weak corrosivity on the steel, which should be taken into cons ideration in the selection of the steel bar.
