摘　　要：针对山区半挖半填路基交界面问题开展研究,简述了山区半挖半填路基土工格栅加筋的种类,并对山区半填半挖各类型土工格栅加筋作用和机理进行探究和分析。同时,结合某典型山区半挖半填路基案例建立数值模型探究不同的土工格栅加筋层数、格栅条的铺设间距等对山区填挖交界面的加筋效果,为山区半挖半填路基交界面多层加筋提供重要的工程指导价值。This paper studies the interface between semi-excavated and semi-filled subgrades in mountainous areas,briefly describes the types of geogrid reinforcement for semi-excavated and semi-filled subgrades in mountainous areas,and explores the effect and mechanism of geogrid reinforcement for semi-excavated and semiexcavated geogrids in mountainous areas.At the same time,a numerical model was established based on a typical case of semi-excavated and semi-filled subgrade in a typical mountainous area to explore the reinforcement effect of different geogrid reinforced layers and laying spacing of grid bars on the interface between fill and excavation in mountainous areas.Multi-layer reinforcement at the interface of semi-filled subgrade provides important engineering guidance value.
