AXIAL BUCKLING ANALYSIS FOR BOTTOM-FIXED PILE
端部嵌固桩的稳定性分析

On the basis of energy method, the study is carried out on axial stability of bottom fixed piles which have three different top abutments and are acted on by the lateral frictional resistance and top load. A series of formulas are developed to solve the stability problem, and critical slenderness ratio of the pile ( cr ) is solved by numerical method. According to the results of data process, simple approximate formulas are obtained to calculate cr
