| 摘 要： | 以河龙高速公路加筋土挡墙为原型,对台阶式加筋土挡墙的结构特性进行了模型试验研究。测试表明:台阶式加筋土挡墙的墙后土压力较小,呈锯齿形分布,明显受台阶卸载的影响;潜在破裂面与0.3H破裂面假定有较大差异,并随挡墙的高宽比变化而变化;变形特征不同于单级直立式挡墙。

| Abstract: | Taking the reinforced soil retaining wall(RSRW) of Heyuan-Longchuan Highway as the prototype,the structural characteristics of stepped RSRW were investigated by model tests.It was shown that when the soil pressure on the stepped RSRW was relatively small,its distribution form was zigzag,and would be affected evidently by unloading function of the step;the potential fracture surface of the stepped RSRW was obviously different from the 0.3H fracture surface proposed by the usual hypothesis,and would change with height-width ratio of the wall;finally,its deformation characteristics were different from the vertical RSRW with single step. |
