英文摘要	The stability problem of high fill slope is one of the hot issues in the field of geotechnical engineering at present, but the relevant theories have not been built up. The paper first execute spatial-temporal analysis to the process of slip deformation as well as its mechanism of high fill slope through monitoring sliding deformation process of #3high fill slope of an airport in mountain region. According to the presumed position of potential sliding surface, back analysis is used to analyses strength parameter of landsilde slip layer, meanwhile finite element software is used to study the relationship between the slope stability and the original foundation treatment of high fill slope, compactness of fill body, fluctuation of groundwater level and reinforcement. The results include: (1) During creep of high fill slope in mountain region, the deformation with obvious lateral displacement mainly focus on settlement, the three-phase law of landslide deformation with time and the characters of cracks spatial evolution in different deformation periods are significant, and the characters are typical artificial loading back stepping landslide. (2) The sliping surfaces are easily generated in filled soil body or weak intercalation in original foundation soil body. The uprising of underground water level can reduce the soil cohesion and slope stability factor massively. (3) Increasing the compactness of filled soil body, lowering the groundwater water level, setting reinforced geotextile can effectively optimize stability of high embankment slope. But the stability of upper filling body is decided by the qualification of the original foundation treatment. (4) Combining the experience and monitoring, the deformation control recommendations and stability evaluation criteria of high fill slope have been proposed. The results can be referenced to high filling standard writing and engineering practice. © 2016, Science Press. All right reserved.
