摘要
黔桂铁路车河车站路基地段,路堤地基处于斜坡上,由于下部粘土饱水,崩坡积粘性土夹杂碎块石,并在丰富的地下水长期侵泡后软化形成软弱地基,为满足路堤边坡稳定性及地基承载力要求,设计采用强夯置换结合支挡技术处理斜坡软基,取得良好效果。
The embankment foundation of Liuzhou-Guiyang Railway subgrade locates on slope. The clay soil at lower portion is water-saturated and the colluvial clay is mixed with gravel and softened due to long time immersion by rich underground water, as a result, the weak foundation is caused. In order to meet the requirement on embankment slope stability and foundation bearing capacity, combination of dynamic replacement with supporting technology is adopted to treat the soft slope foundation and gets good result.
