以湖南某高速公路煤矸石作填筑材料的施工路段 DK127＋720典型断面为工程背景，分析和模拟了三种不同压实度及3种不同填筑高度的煤矸石路堤的 FLAC3D计算模型。计算了在不同压实度和填筑高度下路堤模型的竖向沉降、水平位移以及最大应力值，并对其变化规律进行了研究。根据不同的压实度和不同的填筑高度路堤模型的位移、应力值，分析得出了影响路堤模型的竖向沉降、水平位移以及最大应力变化的关键因素。以现场观测值为依据，对比了数值计算结果与实测结果，得出了两个结果之间的关系。

Based analysis and simulation of three different degree of compaction as well as three different filling height of coal gangue FLAC3 D calculation model of highway construction section as a fill-ing material with gangue DK127 +720 typical sections focus on the next the embankment model of verti-cal height in the different degree of compaction and filling subsidence,horizontal displacement values as well as the maximum stress changes.Value of the reference field observations,comparing the differences of the numerical results with experimental results and a brief discussion of its causes;according to the different compaction and the settlement value of the filling height of embankment model,analyzed the im-pact of embankment model subsidence and stress change some of the key factors of its variation.
