摘要
利用数值分析工具对某失稳边坡破坏过程进行了全过程模拟,并以模拟结果为依据,结合地质条件提出了边坡应急加固治理方案。数值模拟结果与现场实际监测的数据均表明,对于应急工程,在来不及进行二次勘探的情况下,采用数值分析模拟,了解边坡应力分布规律,查找边坡潜在滑动带位置,分析其破坏机制,从而确定合理有效的治理方案,并经治理后监测验证是完全可行的,为应急边坡治理提供了新的思路与方法。
Using numerical analysis tools to simulate the failure process of an unstable slope,and based on the simulation results,combined with geological conditions,a slope emergency reinforcement treatment plan is proposed in the paper.Both the numerical simulation results and the actual monitoring data show that for emergency engineering,when it is not possible in time to conduct further exploration,numerical analysis simulation is used to define the stress distribution law of the slope,find the position of the potential sliding zone of the slope,and analyze the failure mechanism of the slope.Hence a reasonable and effective treatment plan is determined,and the monitoring result after treatment indicates that the treatment is feasible,which provides new ideas and methods for emergency slope treatment.
