摘要
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。
An assessment was made of working principle and bearing capacity computation of cast\|in\|site bored pile in permafrost zone based on summary of research achievements in recent 30 years on pile foundation at permafrost zone, especially Qinghai\|Tibet Plateau by permafrost engineering circle of China. Some advice is raised about factors affecting the bearing capacity of pile foundation and construction technology based on site testing data.
