关于高速公路软土路基沉降及稳定性监测

On the Settlement and Stability Observation of Highway Soft-clay Embankment

我国很多的高等级公路要穿过软土地区,由于软土地基具有特殊的工程性质,软基沉降现象非常显著,因此对软土路基沉降特性的研究是工程中的主要问题之一。本文介绍了软土路基施工中存在的主要问题和路堤施工软土路基观测的目的和内容,总结了路基沉降的观测方法及具体步骤,并结合高速公路工程实例,说明了软土路基沉降的观测方法在实际工程中的应用。

Many highways in China go through soft-clay area,because of the specialty of soft-clay foundation,the soft-clay foundation settlement is significant.Therefore,the settlement feature of soft-clay foundation is one of the most important researching points.The paper introduces the main problems in soft-clay foundation construction and the purpose and content of road embankment construction soft-clay roadbed observation and summarizes the observation methods and specific steps of road embankment settlement.Combining the highway project practice,the paper explains the application of observation of soft-clay settlement at the actual project practice.
