土工格栅技术应用在高填方边坡的几点思考

Applications of Geogrids in a High Fill Embankment

高填方边坡防护治理方法多种多样,由于土工格栅技术日益成熟及经济性较好,现已被广泛运用于高填方边坡治理工程中。对土工格栅高填方边坡治理方案的三个问题进行思考和探讨:1下伏岩土层差异对土工格栅边坡方案的影响;2地基处理对土工格栅边坡的影响;3坡脚处理方案分析,同时提出了解决的方法和建议,以期为土工格栅治理高填方边坡方案提供帮助。

There are many methods have been successfully used in the stability mitigation of high fill embankments.Due to its relatively matured theoretical design analysis procedures and its cost effectiveness,the geogrid is widely used in the high fill embankment as retaining structures.This paper discuss′the three aspects in the embankment stability mitigations：1）the effect of property variation of the subgrade soils 2）soil improvements;and 3）treatment of the embankment toe.The objectives of these discussions are to provide a safe and economical design scheme for the high fill embankments.
