中文摘要：

随着民用航空事业的快速发展,越来越多的机场＂上山＂修建,从而产生了大量挖方及填方边坡.这些边坡地质条件复杂、高度大、形成时间短,其稳定性严重制约和影响到机场的设计、施工和运营.对不同极限平衡法在机场高填方边坡稳定性中的应用进行了对比分析,采用一般条分法、简化毕肖普法、简布法、摩根斯坦~普赖斯法分别对华北地区某机场黄土高填边坡正常条件和地震作用两类工况三种含水量状态下的稳定性进行了分析.结果表明,水对边坡稳定性影响比较大,在边坡设计过程中对于地基土和填筑体选用合适含水量状态下的抗剪强度参数和做好边坡排水设施至关重要;不同的计算方法,稳定系数计算结果不同,简化毕肖普法和摩根斯坦~普赖斯法的计算结果比较接近、一般条分法和简布法计算结果比较接近,而前面两种方法比后两种方法稳定性系数平均大7%左右.

英文摘要：

With the rapid development of the civil aviation industry, more and more airports are built on the mountain, which results in a large number of excavation and embankment slope. These slopes have complex geological conditions, greater height and shorter formation time, whose stability has a serious constraint and effect on the design, construction and operation of the airport. In this paper, we make a comparative analysis of the effect of different limit equilibrium me- thods on the stability of airport high filling slope. By using the Ordinary, simplified Bishop, Janbu, Morgenstern-Price methods, we analyzed the stability of loess high embankment slope ofan airport in north China under the normal condition and seismic work in three moisture states. The results show that water is relatively a large impact on slope stability, and it is important to select slope and embankment soil shear strength parameters under appropriate moisture content conditions and guarantee sound slope drainage.The stability coefficients of different calculations are different.The results of simplified Bishop and Morgenstern-Price methods are relatively close, and Ordinary and Janbu methods calculated results are rela- tively close. However, the stability coefficient of the simplified Bishop and Morgenstern-Price is average 7% larger than the other two methods.
