ZHANG Yuan-fang, CUI Shu-qin. Analysis on vertical bearing capacity of end-bearing pile foundation based on the catastrophe theory[J]. 2007, 28(S1).DOI:
There are a number of solutions to vertical ultimate bearing capacity of single pile
but so far a feasible and economical method of determining the vertical ultimate bearing capacity of single pile has not been presented. So based on the cusp catastrophe theory
the calculating formula of the vertical ultimate bearing capacity of single pile is deduced in this paper by means of static loading test and parabola method. A case history proved that the calculation results are in accordance with the measured results well when the value of the deformation of piles is small
while when the value of that is big
the calculation results will deviate from the measured results. The inference in this paper can apply to practice.
