软土地基固结变形时间长、强度低。在其上修筑的路基常产生较大的沉降，且常因地基的强度不足导致各种工程病害。介绍了软土路基变形监测的主要内容及其基本原则，并结合大广高速公路京衡段LM11标段内的监测结果对软土路基的稳定性进行分析。该研究对软土路基的施工、设计及其稳定性评价具有重要的指导意义。

The soft ground has a long consolidation deformation time and a low strength. It often produces a larger settle- ment that the subgrade built on it. The ground insufficient strength often lead to all kinds of engineering diseases. The main contents and basic principle of deformation monitoring on soft soil subgrade are introduced. Combined with the monitoring results of LM11 section within Jing-Heng contract of Da-Guang highway, soft soil subgrade stability is analyzed. This analysis has an important guiding significance to soft soil subgrade construction, design and its stability evaluation
