高路堤的稳定性不仅受路堤高度、地形条件、填筑材料性质等因素的影响,还与填筑过程有关。为了正确评价沪蓉西高速公路贺家坪连续线K2+710～890段老路拓宽高填路堤填筑过程中稳定性的动态变化,为施工质量控制提供指导,文章选用该路段的典型断面,利用Geostudio2004,分别采用Ordinary法、Bishop法、Janbu法及Morgenstern-Price法,对该断面填筑过程稳定性进行了分步模拟。
The stability of high embankments is not only affected by embankment height, topographical conditions, the nature of filling materials and other factors, but also with the filling process. In order to correctly evaluate the dynamic change of stability during the filling of embankment with widened embankment of K2 + 710 ~ 890 in Hejiaping continuous line of Shanghai-Chengdu expressway, and provide guidance for construction quality control, the article chooses the typical section of this section, Geostudio2004, Ordinary method, Bishop method, Janbu method and Morgenstern-Price method were used to simulate the stability of the section filling process.
