摘要 2022年北京冬奥会新建的国家速滑馆“冰丝带”和国家雪车雪橇中心工程,结构体系复杂,桩基础承受的荷载较大。为了给奥运场馆提供合理可靠的建设方案和技术参数,在施工前开展了原位足尺桩基承载力试验。通过对国家速滑馆工程和国家雪车雪橇工程试桩试验结果的分析,对卵石地层条件下后压浆工程桩提出了控制要求,对山区复杂地基情况下人工挖孔桩的桩长控制提出了建议。 The projects of the new National Speed Skating Hall called "Ice Ribbon"and the National Snowmobile & Sled Center for XXIV Olympie Winter Games in Beijing are of complex structure system,and the design bearing capacties of pile foundations are very large.In order to provide reliable construction plans and technical parameters, the full-scale field tests of pile foundation were carried out before construction.Analyzing the test piles static loading test results for the two projects,the control requirements for post grouting engineering pile under the condition of pebble stratum were put forward,and the pile length of manual post hole digging pile under the condition of complex foundation in mountain area was suggested.
