Abstract: The high absorption tower is constructed in 8 degree high intensity seismic zone and liquefaction site in Inner Mongolia.Designing the pile foundation correctly is the main factor of the engineering success. The wind and seismic load effect which is needed in tower foundation design and the characteristic value of bearing capacity of single pile during normal and seismic liquefaction is analysed, and The load combination of normal operation, waterfilled pressure test, shutdown maintenance and earthquake action is calculated based on Design Code and PKPM Software. It is concluded that seismic action is the control condition of pile foundation design in high intensity area of liquefaction site. As well as the influence of pile foundation thick cap effect on engineering. The results can be reference for the similar projects.
