综合近 3 0年来国内工程冻土学界对多年冻土地区 ,尤其是青藏高原多年冻土区桥梁桩基研究的成果 ,评述冻土区桥梁灌注桩工作原理及承载力计算方法。结合现场桩基回冻过程地温场变化测试数据 ,对桩基承载力的影响因素、施工工艺提出建议。
Based on the research achievements of the domestic engineering permafrost field in recent 30 years on the research of the pile foundation in the permafrost region, especially in the permafrost region of the Qinghai-Tibet Plateau, the working principle and bearing capacity calculation method of the pile in the permafrost region are reviewed. Based on the test data of ground temperature field during pile foundation refreezing process, the factors affecting the bearing capacity of pile foundation and the construction technology are put forward.
