对某高填方机场出现裂缝的边坡进行变形监测,分析监测数据,并结合地质勘探和数值模拟结果,表明该处边坡存在滑坡的危险;分析造成滑坡变形的主要原因是回填加载时增加的主动土压力引发老滑坡重新产生新滑动.因此提出该高填方机场边坡稳定处理措施,以削挖重新回填为主.%With the deformation inspection on a certain high fill slope and the analysis of the data,combining with the result of geological prospecting and numerical simulation,it turned out that the slope is in the danger of landslide.The result of analysis shows that the main reason of landslide deformation is that the new sliding produced by old slope,which is caused by increasing active earth pressure when backfill loading.According to the above analysis,a treatment measure on the high fill slope airport is proposed,which is mainly based on cut and backfill.
