摘　　要：为江苏省某电厂厂区的吹填砂地基寻求合适的地基处理方法,华东电力设计院建议在现场以强夯工法和高真空击密工法作地基处理的对比分析。该文通过对试验过程中水位、超孔压、土体沉降等监测数据的分析,以及对加固完毕后的地基用标贯试验、静探试验及载荷试验进行加固效果的检测分析,结果发现在该地质条件下强夯工法地基加固效果要优于高真空击密工法加固效果,这种结果与试验前的预期并不相符,该文从试验工法和工程地质条件的角度对造成这种不相符的原因进行探索和解释,得出一些具有借鉴意义的结论,为以后类似工程的地基处理提供了相关的工程经验。To get the proper foundation treatment method for dredger fill ground of one electric power plant in Jiangsu province, ECEPDI suggests to conduct the contrast analyses of dynamic compaction and HVDM in field experiment. Through analyzing monitoring data of water level, excess hydrostatic pressureand ground settlement and analyzing the effectiveness of strengthening, this article found that dynamic compaction method is more apprepriate on this geological condition, and this conclusion isn＇t coincident with our anticipation before the experiment. This article will give. some explanations of the noncoincidence from the aspects of geological condition and the experiment method, and get some useful conclusions from the study, and it provides some engineering experiences.
