以珠海市建成的公路软基处理及沉降观测资料为基础,分析指出地基处理不可能消除工后沉降,选择地基处理方法应与地基条件、路堤高度相结合,不同处理方法均需足够的预压,地基沉降规律较符合双曲线关系,工后沉降会引起横坡改变,加筋土桥台是消除“三孔”跳车现象的有效方法。 Based on the data of soft ground treatment and settlement observation in Zhuhai, it is pointed out that it is impossible to eliminate post-construction settlement by foundation treatment. The selection of foundation treatment method should be combined with foundation conditions and embankment height. Different treatment methods require sufficient preloading The law of foundation settlement is more in line with the hyperbolic relationship. Post-construction settlement will cause the change of cross slope. Reinforced soil abutment is an effective way to eliminate the phenomenon of “three holes” jumping.
