碎石桩处理软土路基沉降的有限元分析

The finite element analysis of gravel pile treating soft soil roadbed settlement

软基公路一般具有较大沉降,这是软土基承受载荷能力较差导致的。较大的沉降会使道路损害严重,还会导致交通事故发,因此进行软土基沉降控制研究十分关键。文章从碎石桩作用机理和施工工艺出发,通过PLAXIS有限元软件建立数学模型对软土基和碎石桩处理地基进行有限元分析,得出碎石桩对处理软基公路沉降有较好效果,可为今后软基公路的沉降处理提供理论依据。

Soft soil roadbed highway generally has a larger settlement, because of the bearing ability of soft soil foundation is poor. Larger settlement will make the road damage serious, can also lead to traffic accidents, so it＇s important to research on the control of soft soil roadbed settlement. The article embarks from the gravel pile mechanism and construction technology, through the PLAXIS finite element software to establish the mathematical model to analyze the gravel pile treating soft soil foundation, concluded that gravel pile has good effect to deal with soft foundation, provide theoretical basis for the settlement treatment of highway soft foundation in future.
