| Abstract: | Taking the bridge of some railway special line in the northwest region as an example, a study is made on the construction technology for the deep pile foundation in the collapsible loess area at the bridge site. The experience and the technical parameters on the construction of the pile foundation in the loess area are summarized based on the accumulated data and parameters from the mechanical drilling construction in the loess fractured stratum, strong-weathered mudstone, sandstone mudstone stratum and other unfavorable geological layers, and the construction efficiency of the pile foundation under the same geological conditions is greatly improved thereby. |
