摘　　要：以某拓宽工程为例,通过实际沉降监测数据研究新老路基的不均匀沉降特性,并从理论角度对产生不均匀沉降的原因进行分析与研究,从而提出相应的不均匀沉降控制技术,以便避免或减少不均匀沉降现象发生,确保高速公路的正常运营,且对高速公路路基稳定、使用寿命及使用品质具有重大意义。Taking a widening engineering for example,the uneven settlement characteristics of the new and old roadbed are studied through actual settlement monitoring data,and the causes of uneven subsidence are analyzed and researched from a theoretical point of view,in order to avoid or reduce the differential settlement occurs,the appropriate uneven subsidence control technology is proposed,which can ensure the normal operation of the highway,and can produce a significant meaning for the roadbed stability and lifespan and quality of its using.

关 键 词：拓宽路基 不均匀沉降 控制技术
