technical field

The utility model relates to a device for simulating tidal surge in hydraulic model tests, which belongs to the field of hydraulic engineering model tests. the

Background technique

The coast, rivers and lakes and other entrances and exits are often subjected to alternating impacts such as waves and tides, and hydraulic flow control facilities and related buildings are subject to huge impacts, which can easily cause structural damage accidents. In recent years, tsunami accidents have occurred frequently, and their destructiveness has become more and more serious, causing extremely serious damage to coastal facilities. The all-round simulation of super-strong tide surges and the real simulation of its super-strong impact load have always been the focus of this test. major problem. At present, there is no effective method to quickly and easily simulate the high tidal velocity control of strong tides. Only a large-scale water system and a multi-pump system can be used to simulate low tide head and bottom flow velocity. Due to the limited strength of the simulated tidal head and tidal velocity, The measurement and analysis of strong tidal loads brings huge deviations, which brings great errors to the design loads of tide-blocking buildings, and the inversion effect of tidal surge is not obvious. the
