摘　　要：软土地基沉降是影响高速公路安全性、稳定性、平顺性的重要因素。因此,如何合理的选择软土地基处理方案并有效的控制和预测地基残余沉降量是高速公路沉降区质量控制的关键之一。本文以阿尔及利亚东西高速公路东标段沉降区路基施工为例,对沉降观测监控系统提供了借鉴,并对软基采用浅层处理结合堆载预压的处理方案中的残余沉降量进行了分析。The soft soil foundation settlement is an important factor affecting the safety,stability and ride comfort of expressways.Therefore,how to reasonably select the soft soil foundation treatment plan and effectively control and predict the residual settlement of the foundation is one of the keys to the quality control of the settlement area of the expressway.This paper takes the roadbed construction in the settlement zone of the eastern section of Algeria's east-west expressway as an example to provide a reference for the settlement observation and monitoring system,and analyze the residual settlement in the treatment scheme of shallow treatment combined with preloading of soft foundation.
