摘要
云奉高速公路奉节东立交高填方区边坡规模较大,其稳定性是该工程安全的控制因素。采用有限元强度折减法,对该高填方区的几个关键断面进行了稳定性分析,计算结果表明这几个关键断面的安全系数都大于1.3,该边坡是安全的。通过计算得出了几个安全系数下不同断面的推力,给出了推力的合力作用点,为该填方工程的支挡结构优化设计提供了依据。
The high-filling slope of FengJie east interchange in YunYang-FengJie highway is very large, and its stability is the key factor for project safety. The stability analysis of three key sections is performed by FEM strength reduction methods. The computation results showed that the safe factors of these sections are all above 1.3, i.e., this slope is safe. The pushing forces of these section and the action spot of it can be used as the design basis of the retain wall of this filling area.
