摘　　要：介绍了武英高速软基路段的监测方案,分析了沉降随填土加载的变化规律,当沉降曲线出现向上拐点,路基面临失稳,用监测曲线监控填土高度和加载间隔,以保证路基的稳定安全。监测表明,用薄层轮加法填土,不仅可以加快填土速率,且地基也更为稳定安全。Wuying high-speed soft ground section of the monitoring program was introduced.It was analyzed of subsidence variation loaded with filling.When the settlement curve upward inflection point,roadbed facing instability,with the monitoring of fill height and load curve monitoring interval to ensure the stability of embankment safety.Monitoring show that the filling of thin round of addition can not only speed up the filling rate,and also more stable and secure foundation
