| 摘 要： | 土石混填高路堤作为山区高速公路建设常采用的一种路基形式，其工后沉降控制已成为山区高速公路建设的难题。建立了交通荷载作用下高路堤动力模型，利用有限元软件ANSYS进行了数值仿真分析，研究了车速为100km/h三车道三辆车交通荷载作用下高路堤的沉降规律，分析了土石混填高路堤在其影响下的沉降与循环次数关系，为施工控制沉降措施提供了依据。

| Abstract: | High soil-rock aggregate mixture embankment is one of the subgrade forms used in construction of highway in mountainous area. The control of the post-construction settlement has become a trouble therein. The dynamic model for the high embankment under traffic loads is established to carry out numerical simulation by finite element software ANSYS, through which the settlement law of the high embankment under three-lanes and three-car traffic loads at the speed of 100 km/h is studied ; and the relationship between the settlement and the number of cycles of the embankment under such load. As a result, the basis could be offered for the measures controlling settlement in construction. |
