摘要
桩基质量的好坏在于桩基的合理设计、准确计算、精心施工、科学检测。目前,人们对软土桩基的确切承载机理、承载性能等问题上看法不一,本文从无锡地区软土分布的实际出发,对软土桩基在设计质量控制方面的相关策略进行了研究,为软土地区桩基设计质量提供基础数据和科学依据。
     本文针对无锡地区典型区域的土样,采用了室内土工试验、标准贯入试验、静力触探试验等方法,获得了无锡地区地层岩性和物理力学性质,揭示了无锡地区第四纪土层的基本特性和构造类型。
     本文通过大量深孔钻探岩石试料的室内岩石试验结果总结出无锡地区的硬岩岩性,为无锡地区端承桩的桩尖设计深度提供设计依据。通过无锡地区软土桩基中的单桩承载力机理分析、桩身摩擦力分析和单桩竖向承载力的评判与取值原则分析,结合工程实例,提出了无锡地区软土桩基设计质量控制的基本策略、注意事项、遵循原则,有针对性地指导无锡地区软土桩基设计质量控制,为无锡地区软土桩基工程中在软土地基条件下的基桩设计提供依据。
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.
