| Abstract: | 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. |
