桩基抗冻拔稳定分析及工程应对措施

多年冻土区和深季节冻土区的一些桩基公路桥，在冻胀尤其是极强冻胀作用下，发生不少变形损坏现象。所以研究冻胀力作用下的桩基的受力特性有着很重要的意义。首先分析冻土地区桩基在冻胀力作用下土冻胀特性，其次根据多年的工程实践，提出桩基冻胀防治措施，为今后季冻区的桥梁基础施工提供了有效地实践经验。

Pile Antifreeze Performance Stability Analysis and Project Corresponding Measure

Permafrost zone and deep-season permafrost zone of some pile highway bridge in the freezing,especially under strong frost heave,a lot of damage deformation phenomenon.So study of the role of frost heave under the force of the pile is very important.First of permafrost in the region pile frost heaving frost heaving of the role of soil;then based on years of engineering practice,the proposed control measures pile freezing,frozen for the next quarter based on the bridge construction area to provide an effectiv...
