| Abstract: | According to the characteristics of the system engineering of the Third Ring Road in Xi＇ an city and the geotechnical conditions of construction site, the trial pile tests were carried out on the typical three sites with large diame- ter and large-tonnage reinforced concrete drill-hole pile. The parameters, such as vertical resist compression ultimate bearing capacity and the ultimate friction resistance of single pile, were determined. In addition, the suggestions to constructing and design of boundation piles were proposed based on the analysis of the experimental results. |
