夯实水泥土桩的荷载传递特性

Load transfer behavior of compacted cement soil pile

运用荷载传递法结合Geddes公式计算夯实水泥土单桩的荷载 (Q) 位移 (s)曲线 ,分析单桩Q s曲线随桩长l、桩体极限强度 qu、桩端土压缩模量Es 的变化规律 ,并研究桩身压缩。

Based on the method of load transfer and Geddes formula, this paper calculates the load (Q) settlement (s) curve of compacted cement soil single pile. Then the variational regularity of the Q s curve of a single pile with the pile length l, limit strength q u of pile shaft material, compression modulus E s of soil arround the pile tip are analysed. The relation of compression of pile shaft material, pile end resistance and settlement with the load of pile top are also analysed.
