| 摘 要： | 该文以重庆市某城市主干道岩腔路基工程为背景,运用有限元强度折减法对其进行了稳定性分析,计算出两种工况下路基的破坏模式以及稳定安全系数。通过计算分析,表明工况二相对于工况一的稳定安全系数有较大提高,同时也说明有限元强度折减法是解决岩腔路基稳定性分析问题较好的方法。

| Abstract: | Taking a major urban road rock cavity roadbed of Chongqing as the background,the paper carries out the stability analysis of rock cavity roadbed by strength reduction finite element method.The failure modes and the stable safety coefficients of roadbed at two different working situations are calculated.The calculation and analysis indicate that the stable safety coefficient of working situation II is greater increased than the working situation I.At the same time,the strength reduction finite element method is also explained to be the better method for the stability analysis of rock cavity roadbed. |
