The invention belongs to the technical field of marine engineering concrete material durability test equipment, and particularly relates to a test device for simulating marine environment dynamic andstatic combined concrete loading; compared with the prior art, the device has the advantages that 1, the structure is simple, the installation is convenient, the automation degree is relatively high,manpower and material and time cost are saved, and meanwhile, the overall control function of a control box and the real-time detection and recording function are realized, and the accuracy is improved; 2, an upper water level sensor, a lower water level sensor, a communication water pipe, a test box and a liquid storage box are matched to carry out a dry-wet circulation test, so that clear boundaries of an underwater area, a tidal area and a wave-splashing area can be ensured, the underwater area is always in the soaking environment, the tidal area is located in the soaking and drying environment, and the wave-splashing area is in a spraying environment; and 3, the characteristics of chemical and mechanical coupling and dynamic and static combined loading are considered, so that the testdevice is more suitable for the environment where the concrete is in service, and can be widely applied to the concrete durability test occasions.
