Abstract Research purposes: Taking the high building of Hongqiao Railway Station of Beijing-Shanghai High-speed Railway for example，the summary and analysis of pile types and possible bearing stratums of pile foundations are made in combination with Chinese codes and geology conditions for the purpose of better choice of bearing stratum.
Research conclusions :(1)The distribution regularity of soil is important to select the bearing stratum of the pile foundation. (2 ) The analysis and verification are needed to decide that the soil can be used as the bearing stratum of pile foundation by checking the vertical bearing of individual pile, total settlements volume and the feasibility of pile、 formation. ( 3 ) The Testing pile should be done before formal construction.
