摘　　要：水中含有多种化学组份,有的对混凝土有腐蚀性,有的对腐蚀速度有阻滞效应。阻滞效应对工程防腐蚀是有益的。在进入"十二.五"建设时期,《岩土工程勘察规范》开始全面修订之际,该文依据阻滞效应,对该规范中评价腐蚀强度的浓度法与综合法进行改进,并对硫酸盐腐蚀性评价提出了具体可行的建议。Based on many kind of chemical components containing in water,some are corrosion to the concrete,some have repression effect on corrosion rate,and it has benefit for engineering anticorrosion.In the construction period of the 12th five-year program,the Geotechnical Engineering Investigation Code begins to been revised overall,according the repression effect,the concentration method and comprehensive method of evaluating corrosion strength are improved,and the feasible suggestion are put forward for sulphate corrosion.
