摘　　要：《岩土工程勘察规范》关于水对混凝土硫酸盐腐蚀评价中,有宏观气候对混凝土干湿交替带腐蚀强度影响的规定。该文通过工程实践,对什么是干湿交替带作了说明,论述和分析了微观气候对混凝土干湿交替带的影响,因此,建议《2012年岩土工程规范》全面修订时,应在宏观气候基础上与微观气候相结合,使规范更加完善。In the evaluation of sulfates corrosion of concrete by water in Geotechnical Engineering Investigation Code,it regulates that the macroscopic climate has influence the corrosion strength in concrete dry and wet alternate area.Through engineering practice,it illustrates what is dry and wet alternate area,and discusses and analyzes the influence of macrocosmic climate to dry and wet alternate area of concrete.Thence,it revises that the macroscopic climate should be combined with the microcosmic climate to perfect the code in the revise overall of Geotechnical Engineering Investigation Code in 2012.
