| 摘 要： | 土工格栅作为一种新型的土工合成材料,由于具有高强度、低延伸率等特点而被选作主要的路堤加筋材料.采用通用非线性有限元ABAQUS程序分析了加筋前后路堤的竖向位移和侧向位移.分析结果表明,土工格栅加筋能有效地降低路堤的竖向位移和水平位移,研究成果对软土地基的加筋处理有借鉴意义. |
| 关 键 词： | 土工格栅 软基 有限元 竖向位移 水平位移 |

| Abstract: | Geogrid, a new kind of geosynthetics, is chosen as the main material for embankment reinforcement due to its high strength and low prolongation ratio. The analysis of vertical settlement and lateral deformation of the embankment with the conventional nonlinear finite element program ABAQUS before and after reinforcement by geogrid shows that the adoption of geogrid can effectively reduce the vertical settlement and lateral deformation of the embankment. The research result is of certain reference value to reinforcement of soft clay foundation. |
| Keywords: | geogrid soft clay foundation finite element vertical settlement horizontal displacement |
