| 摘 要： | 沉降观测是验证软土地基设计、指导施工的重要手段,对阿荣旗至博克图高速公路K42+400～K42+500段软土地基处理后现场沉降观测结果及差异沉降量进行分析,表明沉降主要发生在集中填筑期内,沿路基横断面沉降量的分布是不均匀的;验证了采用砂垫层+土工格栅法处理软土地基对减小横向差异沉降和提高地基承载力效果良好。

| Abstract: | Settlement observations are important means to verify the soft soil and guide the design and construction of ground. In this paper, field settlement observations and differential settlement after the soft soil treatment in the section of K42 +400~K42 +500 of Arongqi to Boketu highway have been analyzed. It is showed that settlement occurred mainly in filling period. Distribution of settlement along the base crosssection is uneven. It is verified after the treatment of sand cushion + geogrid, the transverse differential settlement can be reduced and the bearing capacity of foundationgood can be improved. |

| Keywords: | Soft ground settlement observation transverse differential settlement sedimentation rate |
