Arched gravity type retaining wall capable of being mounted in splicing mode and anti-seismic energy dissipation method
The invention discloses an arched gravity retaining wall capable of being mounted in a spliced mode and an anti-seismic energy dissipation method. Each assembly comprises a base, a column body, a tie bar, an arched retaining wall plate and an energy dissipation device. The method comprises the steps that the column body and the base are made of similar materials, the tie bars are installed on the rear side of the column body, and the column body and a soil body behind the retaining wall form a stress whole through the tie bars; the arched retaining wall plates are installed between the adjacent columns and used for resisting lateral soil pressure and transmitting force to the columns and the base. The energy dissipation device can absorb kinetic energy and release the kinetic energy to reset the structure after absorbing the kinetic energy through mutual cooperation and mutual restriction of a damping structure, a high-strength spring and a restraint ring, and can also reduce the frequency and amplitude of absorbing and releasing the kinetic energy, so that the situation that the arched retaining wall plate relatively displaces greatly is avoided, and the service life of the retaining wall plate is prolonged. Serious friction and collision are generated between the base and the column body, and damage to the base and other parts is caused. The gravity type retaining wall is reasonable in structural design, and the risks that the gravity type retaining wall slides, integrally inclines outwards and the wall body is fractured and damaged under the action of an earthquake can be effectively reduced.
一种可拼接安装的拱形重力式挡土墙及抗震消能方法。由若干组件拼接安装而成，每个组件包括底座、柱体、拉筋、拱形挡土墙板、消能装置。方法为：柱体与底座由同类材料制作，柱体后侧安装拉筋，拉筋使柱体与挡土墙后的土体构成一个受力整体；拱形挡土墙板安装于相邻柱体之间，用于抵抗侧向土压力，并将力传向柱体和底座；消能装置通过阻尼结构、高强弹簧和约束环三者相互配合、相互制约，既可以吸收动能，并在吸收动能后释放动能使结构复位，又可以降低吸收动能和释放动能的频率和幅度，以免拱形挡土墙板相对位移较大，与底座和柱体之间的产生严重的摩擦和碰撞，对自身及其它部件造成损坏。本发明结构设计合理，可有效降低重力式挡土墙在地震作用下发生滑移、整体外倾和墙身断裂破坏的风险。
