摘　　要：结合广明高速公路高边坡自动化监控工程,运用数值方法,分析边坡在不同工况下失稳临界状态的基本判据。通过计算该处边坡的安全系数,模拟破坏时的最大位移量,给出了变形量预警的具体标准,对边坡现场监测预警具有实际意义。Combining the automatic monitoring engineering of high slope in Guangming Highway, the basic criteria of the critical state of slope instability under different rainfall conditions are numerically analyzed. The specific criteria of early deformation warning are proposed by calculating slope safe factor and simulating the maximum displacement under the damage of slope. This study has a practical reference to on-site slope monitoring and warning.
