摘要
将强度折减的方法用于开挖过程中边坡稳定的分析采用黄金分割点的方法,给出了开挖过程中边坡稳定安全系数的确定方法;同时考虑剪胀角在开挖过程中对边坡稳定的影响,给出了安全系数随剪胀角的变化过程,为边坡在开挖过程中的加固措施提供可靠的参考价值.
The method of strength reduction is used to analyze the slope stability in excavation process.A method for determining the safety factor of slope stability in the excavation process is proposed by using the golden section method;and the dilation angle on the slope stability is considered.The safety factor of the slope stability changing with the dilation angle is given.It provides a good reference value in slope excavation process with strengthening measures.
