结合某高速公路工程，对土石混填路堤展开现场压实试验，研究在不同碾压遍数和不同填铺厚度下土石混填路堤的竖向沉降、水平位移、基底竖向应力等的变化规律。结果认为：路堤的累积沉降量随碾压遍数的增加表现出先呈快速增长后逐渐稳定的特征，并且在相同铺填厚度下的差异沉降量随碾压遍数的增加而逐渐减小；水平位移和基底竖向应力也表现出与累积沉降量相似的变化规律，但水平位移量明显比沉降量小很多。通过对试验结果的分析，获得了最佳松铺厚度、碾压遍数等压实工艺参数，为该高速公路路堤施工提供了合理的指导。

Based on a expressway engineering,carry out a field compaction test to the embankment filled with earth-rock mixtures,research the variation about the vertical settlement,the horizontal displace-ment,the basal vertical stress,and the degree of compaction under the different compactions times and different paved thickness.The results indicate that with the increase of compactions times,the cumulative settlement of the embankment show a rapid growth in first and then gradually stabilized characteristics, and under the same paved thickness,the difference settlement decrease gradually with the increase of compaction times ;The horizontal displacement and basal vertical stress also show the same change rule as the cumulative settlement,but the horizontal displacement is obviously much smaller than the settle-ment.According to the analysis of the test results,obtained the compaction parameters,such as best fill-ing thickness,compaction times and so on.The parameters provides a reasonable guide to the construc-tion for the highway embankment.
