摘　　要：载体桩是一种新型的桩基施工工艺,具有承载力高、变形小等特点,将载体桩复合地基技术引入高铁路基的地基处理中,将给高铁路基的地基处理提供一种全新的技术。通过载体桩的处理设计方案、施工工艺、重点测试结果(复合地基承载力、单桩承载力、桩土应力)、以及桩间土处理效果等方面介绍了载体桩复合地基在高速铁路液化土地基中的加固效果,为今后的铁路路基设计提供经验和设计依据。Carrier pile is a new construction technology with the feature of high bearing capacity, low deformation. It would be a technological innovation if it could be applied in the high-speed rail foundation treatment. In the paper, based on the treatment design, construction technology, key test results and treatment effect of soil between piles, etc. the application of carrier pile composite foundation in the high-speed rail liquefied soil foundation treatment has been introduced, which could be used as experience and basis for the future design of railway embankment.
