为满足山区高填方机场的建设需求,针对超高挡墙建设的难题,开展边坡深层抗滑敏感性分析.通过计算分析,对比基岩软弱层、层面和反倾结构面的不同组合工况,探究各敏感因素对深层抗滑稳定性的影响,明确最不利组合工况.结果表明:局部发育软弱层对深层抗滑稳定性的影响较小;层面和反倾结构面分布越深对深层抗滑稳定性的影响越小;层面过墙踵,拐点位于墙趾竖直面时为最不利工况.
Analysis of Deep Anti-slip Sensitivity ofHigh Fill Airport Retaining Wall Slope
In order to meet the construction requirements of high-fill airports in mountainous areas,in view of the construction problems of ultra-high retaining walls,a sensitivity analysis of deep slope anti-sliding was carried out.Through calculation and analysis,the different combined working conditions of the weak bedrock layer,the layer and the anti-dip structural plane were compared,the influence of each sensitive factor on the anti-sliding stability of the deep layer was explored,and the most unfavorable combined working condition was determined.The results show that:1)Locally developed weak layers have little influence on deep sliding stability;2)The deeper the plane and anti-dip plane distribution is,the less influence it has on the anti-sliding stability of deep layer;3)The most unfavorable condition is when the surface passes the heel of the wall and the inflection point is located on the vertical surface of the toe of the wall.
