《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。 “Geotechnical Investigation Regulations” on the evaluation of water sulfate corrosion of concrete, there is a macro-climate concrete wet and dry alternating strip corrosion intensity of the provisions. This article explains what is alternating wet and dry zones through engineering practice, discusses and analyzes the influence of microclimate on the alternating wet and dry zone of concrete. Therefore, it is suggested that the “Geotechnical Engineering Standard of 2012” Based on the climate and micro-climate combined to make the code more perfect.
