摘　　要：依托厦沙高速某段高达63.38 m的填方路堤,使用分层沉降仪监测填方路堤的工后沉降,分析其沉降规律。监测结果显示,工后240 d高路堤总沉降量处于0.151~0.191 m。使用有限元软件ANSYS计算高路堤的沉降量,得到工后240 d总沉降值为0.232 m,与监测值接近。数值计算结果所显示的分层沉降规律和监测结果也较为一致。并且计算了不同压实度下路堤工后沉降量,为填方路堤工后沉降计算和控制提供了有益的借鉴。The post-construction settlement of the 63.38 m high embankment of Xiasha highway was monitored using the layer monitoring instrument chronically.And the settlement regularity was analyzed.The monitoring results showed that the total settlement of the high filled embankment was between 0.151 m and 0.191 m after 240 days of completion of the filling.The settlement of the high filled embankment was calculated with finite element software ANSYS.And the simulation results showed that the total settlement of the high filled embankment was 0.232 m after 240 days of completion of the filling,which was close to monitoring.The layered settlement regularity showed by numerical simulation accorded with that of actual measurement.The post-construction settlement of high-filled embankment under different compactness were also calculated by ANSYS software.A helpful references to forecasting and controlling the settlement of high fill embankment was provided.
