compaction

Based on a large amounts of field experimental results,the paper made a study on the construction process of dynamic consolidation compaction,the reasonable laminated thickness of roadbed filling,the compaction effect control and measuring method as well as the economic efficiency of this technology,meanwhile,the applicable condition and extension of dynamic consolidation are presented.

介绍了强夯压实黄土地基及路堤的现场试验方法 ;结合大量的现场试验结果 ,探讨了强夯压实施工工艺、路堤填方合理分层厚度、压实质量控制与检测技术 ,以及强夯压实施工的经济性等问题 ;提出了强夯压实施工的适用条件和范围 。

The test ascertains the tamping parameter and standard of re-dynamic compaction after heavy tamping,so as to instruct the construction of Chongqing Yu-Lin Expressway and achieve the expected results.

以重庆渝邻高速公路常见的泥岩、砂岩和页岩土石混填路堤为研究对象,通过强夯试验研究确定强夯再压实的夯击参数及质量控制标准,用以指导渝邻路高填方路堤的施工并达到预期加固效果。
