对大庆至广州国家高速公路江西龙南里仁至杨村(赣粤界)A段路线中K21+540～+660段和K23+780～+880段红砂岩风化土高填路堤不同强夯加固方案的现场检测结果进行了分析。从面波波速、压实度、地基承载力、压缩模量方面探讨了不同强夯加固方案下的土体加固效果情况,肯定了现场不同强夯加固方案的可行性。对江西省赣南地区红砂岩风化土强夯加固的进一步研究、设计和施工具有一定的指导意义。
For the high embankment of red sandstone weathered embankment of K21 +540 ~ +660 and K23 + 780 ~ +880 in section A of Liren-Yangcun (Jiangxi-Jiangxi Boundary) from Longqing to Guangzhou National Expressway in Jiangxi province, Field test results were analyzed. The effect of soil consolidation under different schemes of dynamic compaction was discussed from the aspects of surface wave velocity, compaction degree, foundation bearing capacity and compressive modulus. The feasibility of different schemes of dynamic compaction reinforcement on site was confirmed. The further research, design and construction of red tide weathered soil in southern Jiangxi Province are of guiding significance.
