摘要
分析了桩基冻拔产生的原因,针对冻土的特殊性和复杂性,介绍了用断裂力学作为解决桩基冻拔问题的手段,并建立冻土桩基作用机制,概念清楚,方法可行,开辟了桩基抗拔稳定研究的新思路,有较深的研究和推广价值。
It analyses the reasons of the generation of pile foundation frost heaving, aiming at the particularity and complexity of frozen soil it introduces that using the fracture mechanics solve pile foundation frost heaving, builds the action system of pile foundation frost heaving, the conception is clear and the method is feasible, and it inaugurates the new thought of research on the uplift stability of pile, and has deep research and prompting value.
