Research On Design Quality Control For Soft Soil Pile Foundation In Wuxi Area

The stand or fall of pile foundation quality can come fromdesign of pile foundation，accurate calculation, careful construction,scientific detection. people have different views In the field of theexact load-bearing mechanism, the properties of bearing of soft soilfoundation. On the basis of the soft soil in Wuxi area, this papermainly discusses in relevant strategies of the quality control aboutsoft soil pile foundation design.For soil sample of representative region in Wuxi area, this paperused laboratory soil tests and standard penetration test and staticpenetration test. The lithology and physical and mechanicalproperties in Wuxi area are obtained, the basic characteristics andtectonic types of quaternary soil in Wuxi area are revealed.Through indoor rock test results of a large number of deep holedrilling rock sample, this paper summarized property of the hardrock in Wuxi area, and provided the design basis for design depth ofpile tip of end bearing pile in Wuxi area. Based on the research ofsingle pile bearing capacity mechanism and pile body friction andsingle pile vertical ultimate bearing capacity, the paper bringsforward basic strategy and matters needing attention and theprinciples of soft soil pile foundation design quality control in Wuxiarea.
