| 摘 要： | 软土地基高速公路工后沉降普遍偏大,结构物与相邻软土地基差异沉降造成路面呈波浪起伏,严重影响交通安全。分别考虑软土地基在CFG桩、袋装砂井、粉喷桩的地基处理方式,分析差异沉对结构物内力分布的影响程度,可为设计计算提供参考。

| Abstract: | The settlement is generally too large after the expressway is constructed in the soft soil subgrade.The different settlement between the structure and the adjacent soft soil subgrade makes the pavement undulate,which seriously affects the traffic security.The article considers the treatment modes of soft soil subgrade for CFC pile,sand bag well and powder spraying pile,and analyzes the influence level of different settlement on inner force distribution of structure,which provides the reference for the design calculation. |
