中文摘要：

以太原市太行路阎家峰路段为工程应用对象,提出并应用一种适于黄土填料高填方路堤的分层碾压与重锤补夯相结合的综合压实技术。通过结合施工进程的土性试验、现场深层沉降监测等试验手段,研究高填方路堤黄土填料的压实特性、重锤补夯的强化机制及路基的综合压实效果。相关土性试验研究结果表明：分层碾压后的土体再经重锤补夯作用后,压实度、压缩模量等参数得到大幅提高,并随填方深度均呈周期性的锯齿形曲线变化形态。沉降监测及分析结果表明：该综合压实技术处理后的路堤工后沉降显著减小,趋于稳定的最大工后路面沉降仅为路堤高度的0.1%,且填方体的自身压缩变形为总沉降的主要组成部分;填方体工后沉降与时间呈对数关系,依此提出填方体工后沉降的预测公式,与实测值吻合较好。

英文摘要：

An integral compaction technique, starting from layered compaction, followed by heavy tamping, which is suitable for effective compaction of loess-filled high embankment was proposed and applied to the Yanjiafeng section of Taihang highway engineering project. During construction, the loess soil characteristic of the fill material during compaction, the heavy tamping mechanism and final effectiveness of compaction were studied with data obtained by in-situ testing of soil samples and deep layer settlement instrumental monitoring. The relative soil testing shows the following： Degree of compaction and compressive modulus are both increased dramatically, and these parameters vary periodically along with the depth of filling material, representing a sawtooth form. It is well demonstrated that the integral compaction technique has effectively reduced the post-construction settlement of the highway embankment, with an impressive settlement of only 0. 1% of the height.of the embankment, with the compression deformation of the embankment being the main component of the total settlement. A logarithmic relationship is found between time and post-construction settlement of the filling body, and the prediction formula is presented. The formula has a good agreement with the measured values.
