Taking a domestic smelter as an example,based on the geotechnical investigation report of the proposed site,four pile foundation schemes are proposed:mechanical rotary hole filling pile,long auger cast-in-place pile,pre-stress concrete pipe pile,sinking tubular and expanded placing pile.The advantages and disadvantages,bearing capacity,and economic indicators of the four pile foundation schemes are compared and analyzed.The comparative analysis results suggest that the main pile type for this project should use ø600 mm long auger cast-in-place pile.For the factories with relatively high local loads or factories with pile lengths exceeding 30 meters,ø600 mm diameter rotary hole filling pile shall be used.
