关于刚性桩复合地基应用的讨论

Discussion on application of rigid pile composite foundation

本文通过对刚性桩复合地基发展历程的梳理,对比分析了刚性桩复合地基和传统桩基础的异同。基于已有设计计算理论和对工程实践经验总结,建议关于刚性桩复合地基的相关规程、规范应补充桩土应力比的最高限值范围和刚性桩复合地基抗震承载力调整系数,以供工程技术人员对刚性桩复合地基进行合理设计计算和工程应用时参考。

In this paper,through reviewing the development history of rigid pile composite foundation,the similarities and differences between rigid pile composite foundation and pile foundation are preliminarily discussed and analyzed.Based on the existing design and calculation theory and the summary of engineering practice experience,it is suggested that in the application of rigid pile composite foundation,the maximum limit range of pile-soil stress ratio and the adjustment coefficient of seismic bearing capacity of rigid pile composite foundation should be considered in relevant regulations and codes,so as to provide a reference for engineers and technicians to design and application the rigid pile composite foundation more reasonably.
