珠江三角洲地区软土路基实用稳定性判别方法

A practical stability analysis method for the soft soil foundation on Pearl River Delta

摘要: 在系统总结分析珠江三角洲地区近二十条高等级公路软基施工填筑监测资料的基础上,结合珠江三角洲地区高含水率软黏土的变形破坏特征,提出一种基于实测沉降数据的稳定性判别方法。使用这种方法不但可以利用表面沉降资料进行稳定性判别,还可以利用分层(深层)沉降资料针对地基中的最软弱层进行稳定性判别。

Abstract: Through the systematic analysis on the monitored data of the soft soil foundation of nearly 20 freeways constructed on the Pearl River Delta,a new method was developed to evaluate the stability of the soft soil foundation by the combination of the monitored data of settlement and deformation characteristics of the soft soil.The stability of the softest soil strata of the foundation could also be analyzed by the new method with the subsurface settlement.
