Anti-seismic earth-retaining wall suitable for microearthquake region as well as construction method thereof

Abstract

The invention discloses an anti-seismic earth-retaining wall suitable for a microearthquake region as well as a construction method thereof. The anti-seismic earth-retaining wall suitable for the microearthquake region comprises an upper structure, a lower structure and an anti-seismic buffer layer; the upper structure is arranged on the lower structure; a plurality of bulges are arranged at the bottom; a plurality of water discharging holes and a fixed plate are arranged in the wall; a water-collecting tank is arranged at the position of the water discharging hole on the back side of the wall; the lower structure is arranged on a gravel cushion layer; a plurality of grooves are formed at the bottom of the lower structure; a damping device is arranged between the bulges and the grooves; steel plates are arranged on the upper part and the lower part of the damping device; the anti-seismic buffer layer is arranged in a backfill layer behind the wall; one end, near the wall, of the anti-seismic buffer layer and the fixed plate are connected together; and water-permeable geotechnical cloth is arranged on the upper surface and the lower surface of the anti-seismic buffer layer. After microearthquake arrives at the wall, the damping device on the lower part of the wall and the anti-seismic buffer layer behind the wall can absorb earthquake ability, so that the damping effect is achieved and harm on the earth-retaining structure by the earthquake is reduced.

Description

technical field [0001] The invention belongs to the field of retaining wall engineering construction, and in particular relates to an anti-seismic retaining wall suitable for microseismic regions, and also relates to a construction method thereof. Background technique [0002] An earthquake is a natural phenomenon in which seismic waves are generated during the rapid release of energy from the earth's crust. According to statistics, there are more than 5 million earthquakes every year on the earth, that is, tens of thousands of earthquakes will occur every day. [0003] Earthquakes can cause direct damage to the ground, mountains, and buildings, as well as secondary disasters such as floods, tsunamis, and plagues. Landslides and avalanches are earthquake damage phenomena that mainly occur in mountainous areas. It is due to the strong vibration of the earthquake, which makes the cliffs that are already in an unstable state collapse or landslide. Although such secondary dis...

Problems solved by technology

[0008] The current retaining wall mainly relies on its own structural characteristics to resist all earthquake forces, lacks a proprietary retaining wall design for earthquake areas, and does not consider energy dissipation and shock absorption during design
