Experimental Analysis of Vertical Bearing Capacity for Cast-in-place to Tamp Broken Stone in Hole Bottom
-
摘要: 通过夯孔桩与直孔桩承载力对比分析，认为夯孔桩经过夯入碎石后，改善了桩端土性质，使桩端阻力成倍提高；提出了夯孔桩极限端阻力的取值范围，为桩基设计提供依据。Abstract: By the analysis of bearing capacity of tamping pile and common pile, it is believed that the resistance force will increase by times because of the improvement of soil properties at pile end after tamping broken stones. The range of ultimate end resistance for tamping pile is put forward, it provides the basis for pile foundation design.
