项目摘要
In order to establish practical design procedures to evaluate seismic stability of different types of retaining walls against high seismic loads, a series of irregular shaking tests was conducted on retaining wall models consisting of six different types.In some tests, after the first failure plane was formed in the backfill, the second failure place was formed at higher seismic loads. This can be explained by considering the effects of strain localization in the backfill soil and associated post-peak reduction in the shear resistance from peak to residual values along a previously formed failure plane. Such behavior has not been observed in the tilting tests and the sinusoidal shaking tests that were conducted on the same models in the previous study.In these tests, reinforced-soil retaining wall models with a rigid full-height facing exhibited a ductile behavior compared to conventional type retaining wall models such as gravity-type, leaning-type and cantilever-type ones. When the model walls started to tilt, concentration of subgrade reactions at the toe of conventional type retaining walls resulted in local failure due to loss of bearing capacity. On the other hand, under similar conditions, tensile force in the reinforcements of the reinforced-soil retaining walls could be mobilized effectively to resist against the tilting displacement.In addition, performance of retaining walls during the 1999 Chi-Chi earthquake was investigated. It was estimated that damage to conventional type retaining walls was caused by permanent ground displacement along surface faults, large-scale slope movement, loss of bearing capacity in the subsoils, excessive inertia force of the wall, and/or insufficient compaction of the backfill. It was also shown that extent of damage to reinforced-soil retaining walls using keystones as a facing was affected by the amount of vertical spacing of the reinforcements under otherwise similar conditions.
为了建立实用的设计程序,以评估不同类型的固定壁针对高地震载荷的地震稳定性,对六种不同类型的固定墙模型进行了一系列不规则的振动测试。在某些测试中,由第一个失败平面组成,在较高的地震载荷中形成了第二个故障平面。这可以通过考虑在回填土壤中应变定位的影响以及沿着先前形成的故障平面沿峰值到残留值的峰值降低的峰值降低来解释。在先前的研究中,在相同模型上进行的倾斜测试和正弦振动测试尚未观察到这种行为。在这些测试中,与常规类型的保留壁模型相比,具有刚性全高的增强的土壤固定壁模型表现出刚性全高的行为,例如,诸如较高的型,精美的型,精美的型和cantile-type和cantile-type和cantile-type和cantile-type。当模型壁开始倾斜时,由于轴承能力的损失而导致传统类型固定壁的脚趾的子级反应浓度导致局部故障。另一方面,在类似的条件下,可以有效地动员加固土的固定壁的增强抗拉力,以抵抗倾斜位移。在1999年CHI-CHI地震期间的固定壁的性能得到了研究。据估计,对常规类型的挡土墙的损害是由沿表面断层的永久地面位移,大规模斜率移动,地下土壤中的轴承能力损失,壁的过度惯性力以及/或反填料压实不足引起的。还表明,使用钥匙岩作为面孔对增强土壤挡土墙的损坏程度受到在其他相似条件下增援部队的垂直间距的影响。
