摘要

Installation and loading tests of mid-size screwed steel pipe piles were executed, and the following results were obtained. 1) It is possible to drive them into and through sand layers having 50 to 70 STP N-values, with no discharge, noise nor vibration. 2) The characteristics of pile penetration are influenced by spiral wing diameter, angle And shape. 3) There is a strong correlation between bearing capacity and torque and It is possible to estimate the capacity from the R_p-value proposed in this paper.
