Damage test device for seawall under action of wave and earthquake loads

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...

Problems solved by technology

[0003] In actual engineering, some seawalls are filled with tidal flats and soil, their geological conditions are poor, and their foundations are soft soil foundations, with poor bearing capacity and low strength, which easily lead to instability and damage

Coupled with many external factors such as earthquakes and waves, it may cause safety accidents on the seawall
