结合带齿筋H-V加筋土挡墙模型试验,在假定加筋土挡墙破裂面的位置及形状的基础上,考虑均布荷载对破裂面的影响,以楔形体的极限平衡理论为基础,推导出在黏着破坏条件下H-V加筋土挡墙筋条临界长度的表达式。探讨齿筋高度以及水平筋间距对挡墙加筋筋条临界长度的影响,提出在相同承载力下更有效的筋材配置方法。结合室内试验,解释H-V加筋土挡墙黏着破坏时的破坏机理。
Considering the location and shape of the rupture surface of the reinforced earth retaining wall considering the model test of the reinforced earth retaining wall with toothed bars, considering the influence of uniform load on the rupture surface, based on the limit equilibrium theory of the wedge, The expression of critical length of ribs in HV reinforced earth retaining wall under the condition of adhesion failure is deduced. The effect of the height of the tooth reinforcement and the distance between the horizontal ribs on the critical length of the reinforcement rib of the retaining wall is discussed, and a more effective method of the reinforcement configuration under the same bearing capacity is proposed. Combined with laboratory tests, the failure mechanism of H-V reinforced earth retaining wall when it is damaged by adhesion is explained.
