某软弱路基冲压与强夯处理对比试验研究

Comparing Analysis on the Impacting Compaction with the Dynamic Compaction when Treating the Same Soft Ground

对同种地基采用不同的方法进行处理,均可能达到处理目的,但其处理效果和对工程的适宜性会有所区别。在某大型公路工程的软弱地基处理中,分别进行了冲击压实处理和强夯处理的试验。在两种施工方法工后检测中,分别对干密度、压缩模量、面层强度等指标进行了对比研究,并对两种方法的工效进行了比较。结果表明:冲压处理的效果和工艺效益均要优于强夯处理。

Different technical for ground treatment produces different results for some project.The best method of treatment is defined by analysis and contrasting on-the-spot test.With the example of a large project,impacting compaction and dynamic compaction are used for ground treatment.The dry density,the compress modulus,the strength of surface layer and the technological benefits are studied on contrast test between Impacting Compaction and Dynamic Compaction.Based on the study,the impacting compaction is the best treat-ment method for this project.
