ON CRITICAL LENGTH OF PILE IN COMPOSITE FOUNDATION UNDER EMBANKMENT OF HIGHWAY
路堤下复合地基临界桩长探讨

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.
