Construction Quality Control of Dynamic Compaction Method Treatment Collapsible Loess Foundation

Abstract:

Through the field test data comprehensive analysis, the construction parameters of dynamic compaction can be obtained.The comparison of the before and after dynamic compaction reinforcement effect shows that the collapsible loess foundation after the dynamic compaction treatment, the soil dry density increases by approximately 10%, void ratio reduces by about 15%,bearing capacity increases by 15% or more and collapsible disappears. According to the construction practice of large-scale dynamic compaction method in the south line of Jinan around the city expressway, discusses the key problems should be noted during the construction process and treatment methods of special sections, quality testing methods and evaluation standards.
