摘要: 通过选取天津地区代表性的场地地下水水质分析和土的易溶盐试验报告资料,对不同含水层及水和土的离子含量及对建筑材料的腐蚀性进行了对比分析,得出中心城区承压水的离子含量普遍高于潜水的离子含量,第一承压含水层的离子含量普遍低于第二承压含水层的离子含量,滨海新区沿海区域潜水离子含量普遍高于中心城区,滨海新区承压水的离子含量与中心城区相比总体上差异并不大等结论,并对天津地区环境类别和如何判定干湿交替情况进行了分析,对岩土工程勘察具有较强的指导意义。

Abstract: This paper presents the corrosion evaluation results on the groundwater and soil samples from Tianjin area. The test items include the water quality analyses and soluble salt in the soils, contents of different ions in the water and soils as well as the corrosion potentials to the construction materials. The test results indicate that, in the center city areas, the ion contents in the artesian groundwater are generally higher than those of in the nonartesian groundwater; the ion contents in the first artesian groundwater are generally lower than those of in the second artesian groundwater. For the ion contents in the non-artesian groundwater, samples from the Binhai New District near the sea shore have higher contents than those from the center city area. However, the ion contents from the artesian groundwater underneath the Binhai New District have no significant different than those samples from the artesian water underneath the center city. This paper also presents the category of regional environments and techniques to determine the alternates of dry and wet conditions.
