Method for improving anti-pulling safety of existing reinforced soil retaining wall
The invention discloses a method for improving the anti-pulling safety of an existing reinforced soil retaining wall. Anti-pulling tie pieces are installed in the existing reinforced soil retaining wall, and anti-pulling anchor rods are added to the existing reinforced soil retaining wall. The design of parameters of the anchor rods comprises the steps of introducing an anti-pulling stability coefficient of the reinforced soil retaining wall obtained before reinforcement; introducing a target anti-pulling stability coefficient required by the reinforced soil retaining wall obtained after reinforcement; obtaining soil pressure according to filler and the load on a subgrade surface, and determining the pull force of the anchor rods; according to the pull force of the anchor rods, determiningthe parameters of the anchor rods. The method takes partial bearing capacity remained by the existing reinforced soil retaining wall into full consideration, the anti-pulling safety of the reinforcedsoil retaining wall is improved by using an anchor rod framed girder project, the existing retaining wall is prevented from being removed, the influence on existing engineering operation is reduced,the engineering investment is saved, the construction period is shortened, and the construction risk is low.
本发明公开了一种提升既有加筋土挡土墙抗拔安全性的方法，既有的加筋挡土墙内设有用于抗拔的拉筋，在既有的加筋土挡土墙中增设用于抗拔的锚杆；其中，所述锚杆的参数设计包括：引入加固前的抗拔稳定系数；引入加固后的加筋土挡土墙所需达到的目标抗拔稳定系数；根据填料及路基面上荷载得到的所述土压力，确定所述锚杆拉力；根据所述锚杆拉力，确定所述锚杆的参数。本发明充分考虑了既有加筋土挡土墙仍保留的部分承载能力，采用锚杆框架梁工程提高加筋土挡土墙的抗拔安全性，避免了拆除既有挡土墙而减小了对既有工程运营的影响，即节约了工程投资，又节省了工期且施工风险小。
