摘　　要：软土一般具有含水量高、孔隙率大、压缩性强、透水性差、强度低的特点,这类土承载后呈现出沉降量大、排水固结缓慢、地基稳定性差的特征,将直接影响这些地区高速公路的稳定性和耐久性。因为关系到行车的安全性、平稳性和舒适性,在此类土上修筑的高速公路路堤对沉降量控制的要求很高。Most soft soil has the characteristics of high water content,large porosity,strong compressibility,poor permeability and low strength. After bearing,this kind of soil presents the characteristics of large settlement,slow drainage and consolidation,and poor foundation stability,which will directly affect stability and durability of expressways in these areas. Because it is related to the safety,stability and comfort of driving,the requirement of settlement control of expressway embankment built on this kind of soil is very high.
