| 摘 要： | 依据不同路段的实测数据，在理论层面，根据填方重力（包括车辆荷载）、填方内纵横向干湿梯度和温度梯度的变化，分析和探讨公路填方路堤边缘纵向开裂产生的机理．公路上填高路堤纵向开裂的形成机理，主要由路堤边坡干湿场和温度场的周期变化，使填方土体产生反复胀缩，导致路堤边坡表层带、过渡带部分土体强度降低，松散、蠕变，在土体重力和车辆...

| Abstract: | This paper will analyze and discuss the reason of the longitudinal crack on the edge of highway embankment fillment according to fill gravity(include vehicle load)and the cracks in fillment to wet,dry and temperature gradient change in theory on data from different section.In order to provide ideas for embankment design,construction,illness treatment and other research fields,to prevent longitudinal crack,reduce treatment losses and guarantee traffic safety. |
