| 摘 要： | 采用模型试验结合数字照相无标点变形量测技术对竖向加筋砂土条形地基的承载力、土压力分布、加筋机理、破坏模式等方面进行了实验研究.结果表明,竖向加筋体长度与加筋体距基础中心点距离对承载力与土压力分布影响较大,竖向加筋地基的加筋机理主要有侧限和阻隔作用,破坏模式取决于竖向加筋体的位置和长度.

| Abstract: | The model test in combination with the non-target digital photography deformation measure technology was carried out to study the bearing capacity,soil-pressure distribution,reinforcement mechanism and deformation pattern of vertical reinforced foundation.The results shows that the length of vertical reinforcement and the distance of vertical reinforcement to foundation have obvious influence on the bearing capacity and soil-pressure distribution,the main mechanism of vertical reinforcement is confinement and obstruction,and the deformation pattern is dependent on the location and length of vertical reinforcement. |
