路堤下复合地基临界桩长探讨
ON CRITICAL LENGTH OF PILE IN COMPOSITE FOUNDATION UNDER EMBANKMENT OF HIGHWAY
【摘要】 分析了复合地基临界桩长的定义及研究现状,通过路堤下复合地基数值模拟,揭示了复合地基临界桩长的客观存在性质,结合宁—通一级公路K102+990断面处复合地基工程实例,通过平面有限元及半解析元数值分析方法,对临界桩长进行了一定程度的探讨。
【Abstract】 The definition and current study situation on critical length of pile in composite foundation are analyzed. By means of numerical analysis,the existence of critical length of pile in composite foundation under embankment of highway is revealed. Take the composite foundation at the section K102+990 of NingTong highway for example,the critical length of pile is studied by means of FEM and semi-analysis method.
