摘要
系统地研究了带抗滑键挡土墙的设计理论,给出了带抗滑键挡土墙设计的新方法,建议了描述墙后土压力随挡墙位移变化而变化的非线性土压力系数计算公式,讨论了嵌岩桩承受水平荷载作用下的荷载-位移关系,并将其运用到带抗滑键挡土墙的设计理论之中,给出了挡土墙的设计步骤。根据具体的工程实例的计算,表明该方法是合理的。
The design theory of retaining walls with anti-slide tie is studied systematically, and a new method on the design of retaining wall is presented. A nonlinear earth pressure coefficient formula of the earth pressure changing with retaining wall displacement is proposed, and load-deformation relationships of anti-slide tie under horizontal loading are discussed. The proposed method is applied to design of retaining wall with anti-slide tie. Through a case study, the results confirm that the proposed method is reasonable.
