超大吨位抗压及抗拔试桩施工工艺

摘要

The paper introduces the construction craft procedure and operation controlling points for the compression resistance trial pile with the largest pulling resistance in China,and sums up the difficulties in the super-tonnage pile foundation pulling resistance design and construction,so as to accumulate experience for the pile foundation construction with similar conditions.%介绍了目前国内抗压、抗拔力最大的试桩施工工艺流程及操作控制要点，总结出了大吨位桩基抗压力，抗拔力设计和施工中遇到的难点，为今后同条件桩基施工积累了经验。
