摘　　要：为提高黄土填料高填方路堤压实质量,在选取典型断面开展理论计算的同时开展沉降监测。监测前期路堤横向各部分沉降变形速度较快,后期逐渐趋缓并达到稳定状态,其中以路堤中部变形最大。路堤中部纵向变形呈现监测前期变形量较大、后期逐步趋稳的变化规律。路堤沉降变形实测值小于理论计算值,说明路堤稳定性良好,达到了预期的压实效果。In order to improve the compaction quality of high fill embankment with loess filler,the settlement monitoring is carried out while selecting typical sections for theoretical calculation. In the early stage of monitoring,the settlement and deformation speed of the lateral parts of the embankment is relatively fast,and in the later stage,it gradually slows down and reaches a stable state,of which the deformation in the middle of the embankment is the largest. The longitudinal deformation in the middle of the embankment presents a change law of large deformation in the early monitoring period and gradual stabilization in the later monitoring period. The measured value of embankment settlement deformation is less than the theoretical calculation value, which indicates that the embankment stability is good and the expected compaction effect is achieved.
