Abstract: Most parameters of concrete showed time variant characteristics, and the early-age volume deformation and cracking of concrete is the result of the concerted action of multi-factors containing chemical, hygral, thermal and mechanical changes. In this paper, the strongcoupling model simultaneously considers hygro-thermo-chemo-mechanical coupling phenomena was adopted to describe the cracking behaviour of sidewall and shiplock mass concrete. Results indicated that the computed results based on the systematic laboratory tests and field monitoring agree well to the field monitoring results, the accuracy and reliability was verified in several civil engineering. By doing this, the computed results can be used to guide the practical engineering design and make the effective measurements to decrease the cracking risk of concrete.
