Abstract： Based on the selection of foundation, Yunnan Science and Technology Museum column height, live load of large structures in soft soil and high intensity area is briefly introduced. Two kinds of pile type (the bored pile and PHC tubular pile) were compared. Pile foundation construction was studied by comparing the pore forming possibility, economy, construction the degree of difficulty, the actual construction situation, and the bearing capacity of single pile. Pile test results show that the construction of PHC tubular pipe is difficult and bearing capacity and pile length can not reach the design requirements. Ultimately bored pile whose construction is more easy and bearing capacity can meet the design requirements was chosen.

Keywords： pile testing; PHC tubular pile; bored pile
