Abstract :
On the basis of the large quantities of jacked tube pile load test research in Zhengzhou city, the ultimate bearing capacity of single pile is obtained based on the Q-S curve test results.Then, the relationship between single pipe ultimate bearing capacity and final pressure of single pile is analyzed by using the mathematical statistics method. Finally , the regions experience formula is established, so as to evaluate the relationship between the Final Pressure of jacked tube pile and the Ultimate Bearing Capacity of Single Pile at the different aspect ratios and the sand layer, which provides an evidence for jacked tube pile of application and promotion in the Yellow River alluvial plain.
