摘要

通过室内拉拔试验研究了格宾网筋土作用特性,利用振动台试验研究了加筋格宾挡墙的动力特性,分析了它在地震荷载下的破坏现象及其动土压力分布规律,并找出其在地震荷载下的最不利部位,提出了加强措施;利用Geo-Studio软件建立人工耦合有限元数值模拟模型,对比分析了振动台试验及相同尺寸的有限元数值模拟模型,研究加筋格宾挡墙的动力特性;分别建立了4种相同尺寸的模型,研究加筋格宾挡墙体系在整体受力体系中格宾挡墙及墙后加筋的影响。
The properties of gabion mesh Role properties are examined by the indoor pull-out test,the dynamic features of reinforced gabion retaining wall analysis are studied through shaking table test,analyzing the destruction under seismic loading and the failure law of its ground breaking pressure,to find out the worst part of reinforced gabion retaining wall under seismic loading and provide Related measures for enforcing the wall.Geo-Studio software,using an artificial coupling finite element numerical simulation model,compares analytically the results of shaking table model test and the finite element numerical simulation with the same size,to further study the dynamic characteristics of reinforced gabion retaining wall,Study reinforced gabion retaining wall system in the overall force system gabion retaining wall and the wall reinforcement effects.
