What kind of retaining wall is the most seismic?

Self-embedded retaining wall is the patent achievement of Jiangsu Youningshubuoke Company. It is an integral flexible structure composed of self-embedded retaining blocks, anchor bars, geogrids and gravel layers. Each component of the structure has extremely high strength, and it is located on the foundation of flexible aggregate or strip concrete, and it has extremely high adaptability when it encounters small-scale foundation settlement or static and dynamic loads (such as automobile loads and earthquake loads). In case of earthquake, water scouring or ship collision, there is great flexibility between the gravel layer and the self-embedded block in the structure, which can be moved appropriately to unload and reduce the impact on the retaining wall. Therefore, when a small earthquake comes, the structure is basically in an elastic state and will not be destroyed.

Self-embedded retaining wall is an integral mixed structure formed by geogrids and retaining blocks with good ductility to enhance the ductility of the structure. It is ensured that the strength of the structure can be basically maintained during plastic deformation during moderate or large earthquakes. According to the introduction of the technical personnel of Youningshubullock, the ductility of the self-embedded retaining wall structure can be further enhanced by adding structural columns, that is, a reinforced concrete structural column is set at regular intervals in the direction of the retaining wall, and the lateral earth pressure borne by the retaining blocks between the structural columns is transmitted to the structural columns, which then transmit the force to the foundation, and the foundation then transmits the force to the foundation, so as to dissipate the earthquake energy by the ductility of the structure, so as to survive the disaster without collapse.

In addition, the self-embedded retaining wall is convenient to construct, which can shorten the construction period by 3/4; Can quickly restore ecology; The comprehensive cost can be saved by 3-6%. Meet the requirements of tight construction period and rapid ecological restoration in earthquake areas. At present, the self-embedded retaining wall structure has been successfully applied in many other earthquake-prone areas besides Tangshan, such as the second phase regulation of Panyang Lake (Jiangxi Jiujiang earthquake with M = 5.7), Simao River regulation (Yunnan Pu 'er earthquake with M = 6.4), Feidong Dianbu River Project (Anhui Feidong earthquake with M = 3.5), Jurong section regulation of Ningchang Expressway (Jiangsu Jurong earthquake with M = 3.6) and Shuangliu Lanshan Valley Project (Wenchuan, Sichuan
