摘要

针对目前土工格栅加筋挡土墙动力特性理论研究相对较少这一情况,通过数值分析方法,对土工格栅加筋挡土墙在"Loma Prieta"地震动荷载下面板的侧向位移、表面沉降以及位移场特征进行了初步研究,研究表明土工格栅加筋挡土墙在动荷载下具有良好的抗变形性能。研究结果充实了土工格栅加筋挡土墙动力特性研究理论,有利于工程实践。
The theoretical study on dynamic behavior for geogrid reinforced retaining wall is still limited at present.In view of this situation,by using numerical analysis method,a preliminary study was made on the lateral displacement,the surface subsidence and the characteristics of displacement field of geogrid reinforced retaining wall under the "Loma Prieta" seismic load.The results showed that the geogrid reinforced retaining wall has good anti-deformation performance under dynamic load.The results of study enriched the theory about the dynamic characteristics of geogrid reinforced retaining wall,and are helpful to the engineering practice.
