摘要
地下水对建筑材料的腐蚀致使诸多建筑物不能达到预期使用年限甚至发生严重事故,为了防止此类危害的发生,在岩土工程勘察中,必须对能触及到建筑基础或构筑物的水体采样、进行水化学成分分析、评价地下水的腐蚀性,为工程设计提供依据。通过采取苏州吴中区某一建筑场地地下水样,有针对的测试其中部分化学成分的含量,对照相关国家规范,判断此地地下水对建筑材料(主要指混凝土和钢筋、钢结构)的腐蚀性及腐蚀强度,为工程防腐提供依据。
The corrosion of groundwater to construction materials causes many buildings not to the expected life or damaged. In order to prevent the disaster and provide basis for engineering design, it is necessary to sample, analyze the chemical components, and evaluate the corrosion of the groundwater which impacts the building foundation or structures in investigating of geotechnical engineering. According to sampling the groundwater in a venue of SuZhou, the article purposely tests the content of part chemical components and iudges the corrosion of groundwater and its degree to construction materials （the main is concrete, reinforce and steel structures） according to the related national norms. The result is can provide the basis for engineering preservation.
