Experimental research on bearing capacity of PHC pile in Caofeidian area TangShan city HeBei province

The article studied the bearing capacity of PHC pile in soft foundation,distribution rules of shaft and tip resistance by static loads test with strain gauges mounted at the interface of soil layer.It is concluded: 1) The values of shaft resistance are very small within the cover depth of the first soil layer because of unconsolidated.2) Axial force transmitted from top to bottom.The values of shaft resistance have some connected with depth.3) Test piles with end-resistance no more than 5% of to...
