| 摘 要： | 用有限元法对利用双向土工格栅加筋桥头路堤,从而控制桥头跳车的问题进行研究。分析加筋层间距对桥头路堤的沉降、竖向附加应力分布、土工格栅的拉应力和拉应变的影响规律。结果表明,以合理的方案对桥头路堤作加筋处理,可以有效控制桥头路堤的沉降,并使得桥台与路堤间的沉降能平顺过渡,为控制桥头跳车创造了有利条件。 |

| Abstract: | In this paper,the finite element method is used to study bridgehead embankment reinforced by two-way tensioned geogrid for the purpose of controlling vehicle bumping at bridgehead and to analyze the laws of influences of the geogrid layer spacing on the settlement,vertical additional stress distribution of the embankment and on the tensile stress and tensile strain of the geogrid.The results show that the handling of the bridgehead embankment by proper arrangement of geogrid reinforcement layers can effectively control the settlement of the embankment,provide smooth transition between the settlement of bridge abutment and embankment,and therefore create favorable conditions for controlling vehicle bumping at the bridgehead. |
| Keywords: | vehicle bumping at bridgehead two-way tensioned geogrid embankment reinforcement numerical analysis |
