【摘要】 在前人研究的基础上,对加筋土挡土墙试验原型进行了改进。以不同超载下墙面板的土压力、墙面板的位移、拉筋的拉力等变化过程为依据,对加筋土挡土墙的工作机理进行了探索。测试结果分析表明:加筋土挡土墙通过发生一定的侧向位移使拉筋发挥作用;墙面板所受的土压力随着竖向土压力的变化而变化,呈现先增大再减小的过程;拉筋对土体的侧限作用发挥到一定程度后,墙面板的土压力将要开始随着拉筋内力的增大而减小;拉筋的内力越大,拉筋对土体的侧限作用发挥越充分,墙面板的位移增加越缓慢。更多还原

【Abstract】 On the basis of previous studies,Earth Retaining Wall Testing Prototype was improved.According to the transformation process of different earth pressure of an overloaded Shingle nail,displacement of a Shingle nail and the tension of Lacing Wire,the Matrix Raid of Reinforced Earth Retaining Wall is explored.The analysis of the testing results shows: Reinforced Earth Retaining Wall enables lacing wire to work by a certain lateral displacement.Earth pressure of Shingle nails changes with the shift of Vertical earth pressure,showing a process of increasing firstly and decreased then.When the Lateral Restraint Function of Lacing Wire goes to a certain extent,the earth pressure of the Shingle nail will decrease with the increase of internal force of Lacing Wire.The stronger the internal force of Lacing Wire is,the fuller the Lateral Restraint Function of Lacing Wire is,and the slower the replacement of the Shingle nail is.更多还原
