Abstract: In order to study the gobi environment influence on the development of the strength of concrete piers,the raw material were tested first,and then the four different curing methods and concrete bridge piers under different curing days in different age of compressive strength and tensile strength were tested and analyzed,the curves of concrete strength in different ages were fitted,and the calculation formula of fitting error and practical was verified. The results show that:①under the same curing days,the standard curing strength is the highest,maintenance of new materials,geotextile maintenance,natural curing second;②under the same curing method,the most reasonable maintenance days is 14 d;③under the same curing days,according to the maintenance of new materials,geotextile curing,the order of the natural curing ratio gradually increases,the greater the tension and compression ratio,the better the crack resistance is;④through the error analysis and formula for practical verification,fitting formula meets the requirements,the strength calculation can be performed.
