Abstract:

In order to research further on the pile-soil interaction mechanism and the methods to determine the vertical bearing capacity of prestressed concrete pipe pile, taken three projects of the prestressed concrete pipe pile in Changchun area as examples, the squeezing effect of pile to soil and the resistance of pile tip resistance are simulated numerically and tested by loading tests. It is shown that the side friction and the tip resistance are together produced to support the top load of pile in process of pile pressed into subsoil, and thus cause compressional deformation in the subsoil around the pile and near the end of pile. With increasing in depth, the top load of pile will increase gradually, and the bigger diameter of pile is the larger top load is. The proportion of tip resistance to pile bearing capacity tends to decline in regular with increasing depth of pile. According to the relationship between the proportion of pile tip resistance to single pile bearing capacity and the depth of pile, a new method to determine the bearing capacity of single pile is suggested in this paper. The method is feasible and applicable in Changchun area as the ratio of its calculation values to the results from empirical formula is between 0.57 and 1.26.

Key words: pressured pile concrete pipe, numerical simulation, characteristic value of single pile bearing capacity
