利用静力触探指标合理选择预制桩型的探讨

Probe on Rational Selection of Precast Concrete Pile by Using Index of Cone Penetration Test

当工程设计采用混凝土预制桩时,对于以黏性土、粉土、砂土为主地基土的非端承桩,可利用静力触探指标确定合理的预制桩身强度及桩型,避免因桩身强度不够或桩端持力层不正确而在施工过程中造成工程事故。

Pile strength and type can be rationally determined by using index of cone penetration test for the non-point bearing pile in the foundation soil predominated in cohesive,silt and sand soil when the precast concrete piles are used in the projects,and prevent from the engineering accident resulted from the insufficient strength of the pile and the incorrect pile tip bearing stratum.
