| 摘 要： | 借助三维有限元计算机模拟,对云奉高速公路奉节东立交高填方边坡及其支挡结构进行了安全评价.通过有限元强度折减法得到了边坡的安全系数,并且对支挡结构在不同安全系数下的应力,位移和内力等方面进行了计算.基于材料力学提出一种利用三维有限元求解桩内力的简单方法.计算结果表明该边坡晷其支挡结构整体稳定,但局部存在变形过大和超载的问题,并给出了相应的解决办法.

| Abstract: | By means of three dimensional finite element numerical simulation,the safety evaluations of high fill slope and its retaining structure of Fenjie east overpass in expressway from Yunyang to Fenjie are carried out.The safety factor is obtained by strength reduction finite element method,and the calculation results for stress,displacement and internal force of retaining structure under different safety factor are obtaind.Based on the knowledge of material mechanics,a simple method to calculate the internal fo... |
