Variable cross-section thread pile is a new type of piles applied in ground improvement. The vertical bearing characteristics of variable cross-section thread pile are studied by means of laboratory model test and numerical simulation. The difference of bearing characteristics between variable-section thread piles and ordinary straight piles and plain cylindrical piles is analyzed. And the influence of thread structural parameters and foundation soil parameters on vertical bearing capacity of variable cross...
