某电厂工程存在部分填土地段需要判断是否经过了强夯。本研究充分利用周边已有的地层检测资料,采用原位测试、室内试验与秩和检验相结合的方法,针对回填土的强夯判别问题进行了检验分析。过程中选取土的干密度和标准贯入试验击数两个指标进行分析,以判定回填土是否经过强夯。根据分析结果,判定该地段回填土已经过夯实。经过后续工程验证,表明以上分析结果准确,这种分析方法是合理的
A power plant project there is some landfill need to judge whether after the dynamic compaction. In this study, we make full use of the existing formation detection data in the surrounding area, and use the method of in-situ test, indoor test and rank sum test to test and analyze the dynamic compaction of backfill soil. During the process, the dry density of the soil and the standard penetration test number of two indicators were analyzed to determine whether the backfill soil had been subjected to dynamic compaction. According to the results of the analysis, it is determined that backfilling of the lot has been compacted. After the follow-up project verification, indicating that the above analysis is accurate, this method of analysis is reasonable
