Abstract

Abstract

It is introduced that the contrast satic load test of PC pipe pile with tooth pitch with the one of regular smooth surface pipe pile on two sites in Kunming, as well as the unique technical capability of a multi-usage drainage pipe pilewith tooth pitch is introduced. It is suggested that the introduction should propel the new construction technology which can make full use of the earth frictional resistance, effectively improve load-bearing capacity and save investment,material and energy.
- pipe pile with tooth pitch,
- contrast test,
- frictional resistance,
- mechanical lock effect
