| 摘 要： | 桥头跳车现象是公路中常见的病害之一,它的存在严重影响了行车的舒适性,降低了车辆的行驶速度和道路的通行能力,加剧了车辆及桥台构造物的损坏。从台背过渡段路基产生沉陷的原因出发,通过建立三维空间模型,应用有限元法对产生不均匀沉降的可能影响因素进行了计算分析,并在此基础上给出了台背过渡段纵向处理的长度范围要求。

| Abstract: | Vehicle bump at head of bridge is one of common diseases in highway.It seriously affects comfort of driving,reduces running speed of vehicle and traffic capacity of road,moreover speeds up damage of vehicle and abutment.Proceed from reasons the subgrade at abutment back's transition yields the settlement,through establishment of three dimensional space model,the paper calculates and analyses occurrence of unequal settlement,and gives the requirements for longitudinal treating length at abutment back's transition. |

| Keywords: | Vehicle bump at head of bridge Finite element method Transition from road to bridge Remaining settlement Compactness Modulus of deformation |
