Embodiment 1

[0029] Such as figure 1 As shown, a seawall damage test device under the action of waves and earthquake loads includes a model box bottom plate 6, a base 18 and a model box 3, and the material of the model box 3 is plexiglass. There is a building model in the simulation box 3, and different water levels can be simulated upstream and downstream of the building model.

[0030] Such as figure 1 Shown, building model is the trapezoidal wooden case of top opening, and it comprises baffle plate one 14, baffle plate two 15 and baffle plate three 16, and left side plate 12, right side plate 13. Baffle plate one 14 and baffle plate two 15 are arranged in parallel, and are respectively installed in the upstream position of the left and right side plates of wooden box through draw-in groove one 19 draw-in groove two 20 slides, and the parallel spacing of the two is designed according to actual needs. Baffle plate three 16 is slidably installed in the downstream position of the left and...

Abstract

The invention discloses a damage test device for a seawall under the action of wave and earthquake loads, and belongs to the field of seawall slope damage. The device comprises a computer controller,a cable, a model box, a water injection port, a rubber plug, a model box bottom plate, a model box bottom plate handrail, a model box bottom plate clamping groove, a wave maker, screws, a steel sheet,a left side plate, a right side plate, a first baffle, a second baffle, a third baffle, an earthquake simulation vibrator, a base, a first clamping groove, a second clamping groove and a third clamping groove. The device can be used for carrying out a damage test on a seawall under the action of a sea wave load, carrying out a damage test on the seawall under the action of an earthquake load andcarrying out a damage test on the seawall under the combined action of the sea wave load and the earthquake load. The device can be used for researching the influence of seawall damage rules under theaction of the wave load and the earthquake load; and great prospects are realized in the aspect of exploring the damage of the seawall under the wave load condition.

Description

technical field [0001] The invention belongs to the technical field of seawall slope failure experiments, and in particular relates to a failure test device for seawalls subjected to wave and earthquake loads. Background technique [0002] The sea area in the eastern part of my country is vast, with a total coastline of about 32,000 kilometers; the land coastline is about 18,000 kilometers, and more than 6,500 coastal islands form a coastline of 14,000 kilometers. The seawall is an important embankment engineering measure built to prevent storm tide water and waves from invading the protected area and to reduce wind, wave and tidal disasters. As a wave-proof structure, the seawall not only bears the action of waves, but also blocks the tide. Slope-type seawall with light slope protection such as dry masonry or mortar masonry on the facing surface of some seawalls. During the construction, the earth shall be piled up first, and then the slope protection shall be built. The...
