文章基于冲击压路机在含石量很高(60%～70%)的土石混填高填方路基施工中的应用实践,对路堤的沉降变形、干密度、孔隙比以及影响深度进行了试验研究。阐述了高含石量土石混合料的特性、土石混填路基施工参数及质量评价控制指标;同时根据强夯试验的结果,给出了强夯加固红砂岩高路堤的施工参数。
Based on the practical application of impact roller in the embankment filled with high content of rock and soil filled with high fill (60% -70%), the settlement and deformation, dry density, void ratio and depth of influence of embankment were studied. The characteristics of high-content stone-soil mixture, the construction parameters of soil-stone mixed embankment and the evaluation and control indexes of quality are expounded. According to the results of dynamic compaction test, the construction parameters of high-strength consolidation of red sandstone high embankment are given.
