Experimental Study on Friction Capacity of Pile-Stabilized Soil Interface
The pre-bored grouted planted (PGP) pile is a composite pile foundation consisting of a PHC pile and the cemented soil around the pile. In this research, the industrial solid waste such as fly-ash, slag, gypsum were adopted to manufacture stabilized soil. A series of unconfined compressive strength (UCS) tests and pile-stabilized soil interface shear tests were conducted to investigate the frictional capacity of pile-stabilized soil interface. The test results showed that the strength of stabilized soil with mass ratio of 5% cement, 15% slag and 2.5% gypsum was 1210 kPa after being cured for 3 days, which was 7.74 times the strength of cemented soil with 20% cement content. There was no direct relationship between the peak skin friction of pile-stabilized soil interface and the strength of stabilized soil. The peak skin friction of pile-stabilized soil interface was 31.2 kPa for the stabilized soil with 10% cement, 10% slag and 2.5% gypsum, which was 1.24 times the peak skin friction of pile-cemented soil interface.
