针对处于古滑坡体内的四川雅泸路磨房沟隧道,考虑了挡墙、反压、卸荷、锚喷、抗滑桩等多种处理方法,利用极限平衡理论,在同一模型,同一参数的情况下,计算衡量边坡稳定性的指标——安全系数,来确定方案的可靠性。由于计算的精度有限,单独的安全系数不具有太大意义,通过对多个方案计算结果的横向比较,可以有较直观的效果。 Aiming at the Masteong tunnel in Yalu Road, Sichuan Province, a variety of treatment methods such as retaining wall, back pressure, unloading, anchor spray and anti-slide piles are considered. Based on the theory of limit equilibrium, in the same model, In this case, calculate the measure of slope stability - the safety factor to determine the reliability of the program. Due to the limited accuracy of calculation, the safety factor alone does not make much sense. Through the horizontal comparison of calculation results of several schemes, it can have a more direct effect.
