通过室内加筋土挡墙模型试验对墙面土压力及筋条拉力的测试，探讨了加筋土挡墙的工作机理。结果表明，加筋土挡墙墙面板上所受的土压力并不是传统的“主动土压力”，在一定的加筋率及加筋长度条件下，墙面板的侧向变形能有效减小墙面板土压力，有可能实现“零土压力”
Through the test of the indoor reinforced earth retaining wall model tests on the earth pressure and the tensile force of the ribs, the working mechanism of the reinforced earth retaining wall is discussed. The results show that the earth pressure on the reinforced earth retaining wall is not the traditional “active earth pressure”. Under the condition of certain reinforcement ratio and reinforcement length, the lateral deformation of the wall can effectively reduce the wall pressure Panel earth pressure, it is possible to achieve “zero earth pressure”
