摘要: 基于软土区超长桩荷载传递特性的研究,考虑了表层土的软化效应,并对双曲线模型进行了相应的改进,推导出了超长桩荷载与沉降关系的解析解,并给出了底部有沉渣的超长桩的计算公式,提高了理论推导的精确性,最后通过算例验证本文计算结果与实测结果较为吻合,为实际工程计算提供参考。
Abstract: This research is based on the passed characteristics of the super-long pile load contains in the soft soil district, including softening corresponding of the surface soil. Besides, the research has improved double curve model and has derived out the analytical solutions of the relationship between super-long pile load contains and settlement. What’s more, the calculation formula of the super-long pile whose bottom has sediment has been found out, which has improved the accuracy of theoretical derivation. Finally, a numerical example is given to show that the calculated results are consistent with the experimental results, which provides the reference for the practical engineering calculation.
