| Abstract: | A new method for calculating the uplift ultimate capacity of undisturbed soil foundation is deduced and presented based on the limit equilibrium theory,Mohr-Column yielding criterion and the circular failure surface equations recommended by the standard DL/T 5219—2005 ＂Technical specification for foundation design of overhead transmission line＂.A corresponding numerical computation program is written with the language Matlab.Comparison and verification is performed by the lab modeling tests,in-situ test and other theoretical calculating methods,which indicates that this new method is able to accurately calculate and predict the uplift capacity of undisturbed soil foundations. |

| Keywords: | transmission line undisturbed soil foundation uplift capacity failure surface limit equilibrium method numerical computation |
