Outline
In view of the lack of research on the creep characteristics of hydraulic concrete in water from mesoscale scale, a meso-finite element model of concrete specimen of "aggregate-mortar-transition layer" was established. Based on the test data of tensile and compressive creep in water, the method of "orthogonal design-neural network-meso-finite element calculation" was adopted to implement the inversion analysis of the tensile and compressive specific creep of hydraulic concrete specimens at mesoscale. Finally, the relationship between tensile and compressive specific creep of hydraulic concrete and mortar was compared. The results show that the variation law of tension creep degree of hydraulic concrete in water is similar to that in sealed. The creep degree of mortar water is 2.4 times of hydraulic concrete water under conditions of tensile and compressive creep.
