Background
The damage of the bridge caused by the earthquake is mainly caused by the damage of the earth surface and the shock damage of the bridge. The surface destruction has the phenomena of ground crack, landslide, bank slope slip, sandy soil liquefaction and the like. Ground cracks can cause shortening, lengthening or sinking of the bridge span. In steep mountainous areas or sandy soil and soft clay river banks, collapse, bank slope sliding and falling of mountain stones caused by strong earthquakes can damage the bridge. At shallow saturated and loose sandy soil, the sandy soil is easy to liquefy under the action of earthquake, so that the bridge suddenly sinks or sinks unevenly, and even topples over. At the slope soil bank or the ancient river channel, the phenomena of bank slope slippage, cracking, collapse and the like are often caused by earthquakes, and the bridge is damaged. The earthquake damage of the bridge is caused by that the bridge generates horizontal and vertical vibration due to the earthquake, so that the bridge members are damaged and destroyed, and even the bridge is collapsed.
