加筋土挡墙工作机理的室内试验研究

Experimental Study of the Fundamental Mechanism of Reinforced Earth Retaining Walls

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”

An experimental study was conducted to assess the pressure on the facing and tensile force of reinforcement of reinforced earth retaining walls. The fundamental mechanism of reinforced earth retaining walls was researched. The results of model tests show that the pressure on the facing is different from the traditional active earth pressure on the gravity retaining walls. The lateral displacement of facing of reinforced earth retaining walls can reduce the pressure on facing , and even may become zero when it subjected specified degree and length of reinforcements.
