摘 要:
本文首先通过对几种不同压实度的红层填料路堤的室内离心模型试验与数值计算分析，确定最合理的压实度为0．93；然后对用压实度为0．93填筑的红层泥岩路堤进行现场碾压试验，确定了碾压参数；最后对达到压实度0．93的红层泥岩路堤进行沉降监测，监测结果表明，红层泥岩填筑路堤本体压密沉降占填土高度的0．7～0．8％，且完成的时间较快。[著者文摘]

Abstract:
According to the settlement of embankment filled with red mudstone as mentioned, this paper carried out indoors centrifugal model testing and date calculation of embankment packed with different compaction degree of red packing material, gained the most feasible degree is 0.93; Taking in-situ roller compaction with it, the roller compaction parameter is presented; Filially based on the settlement monitoring of embankment filled with red mudstone （the compaction degree is 0.93）, The compaction settlement of embankment filled with red mudstone is 0.7 - 0.8 percent of the height of embankment, and finished in a short time.[著者文摘]
