摘　　要：为探索新型格宾墙相较于传统矩形格宾墙在受力特性方面的差异性,基于离散元分析方法,分别对两种不同格宾墙结构形式在均布荷载作用下的破坏机理进行了研究。离散元模拟结果表明:两种格宾墙在墙背处均产生背离填土方向的位移,不同的是梯形格宾墙产生的横向位移较小,梯形格宾墙的受力及稳定性要优于矩形格宾墙。In order to explore the difference between the new Gabion retaining wall and the traditional rectangular Gabion retaining wall in mechanical property,the failure mechanism of two different Gabion retaining wall structures under uniform load was studied based on the discrete element analysis method.The results of discrete element simulation showed that the displacement of the two kinds of Gabion retaining walls deviated from the filling direction at the back of the wall,but the transverse displacement of the trapezoidal Gabion retaining walls was small.
