低能量强夯联合真空降水加固粉土地基施工参数研究

Construction Parameters Study for Reinforcement of Silt Foundation by Low-energy Dynamic Compaction Combining with Vacuum Dewatering

通过对试验区选用不同夯击能、布点方式、夯击次数、降排水条件及填土方式等施工参数进行低能量强夯试验,并对强夯试验前后采用多种监测和检测手段进行测试。应用统计分析方法对试验结果进行对比分析,讨论了强夯施工参数的变化对粉土地基加固效果的影响,提出了强夯加固粉土地基过程中有关施工参数选取方面的一些建议。

Authors introduce experiment of low-energy dynamic compaction compared with different construction parameters of dynamic compaction energy, stationing ways, dewatering conditions and fill ways. Various methods of detection and monitoring are taken to test the result after the experiment contrast with that before the experiment. The results of experiment are analyzed comparatively by statistic algorithm. The influence of compaction effect on reinforced silt foundation is discussed with the alternation of the construction parameters. Some suggestions are induced about how to prefer the construction parameters of dynamic consolidation used to reinforce silt foundation.
