基于变形协调原则的打桩控制贯入度计算

Penetration Calculation of Piles Based on the Principle of Deformation Coordination

基于Hiley打桩公式,考虑地基土对桩的压缩影响,按变形协调原则,提出了控制贯入度计算公式,经与试沉桩资料对比分析,具有较好的吻合性。本计算公式对合理确定打桩控制贯入度具有一定的参考价值。

Based on Hiley piling formula, and considering the compressing impacts of foundation soil on piles, this paper establishes a formula for penetration of piles according to the principle of deformation coordination. Comparing with the data of test piles, the calculating results show better consistency. Thus, the calculation formula presented may serve as a reference for determining reasonably penetration of piles.
