| Abstract: | The results concerning 70 static load tests of auger bored cast with pressure concrete piles are presented and the values of shaft friction and toe resistance are proposed. The results of 8 static load tests of auger bored cast with pressure concrete pile composite foundation and two static load tests of single piles are also described. According to the bearing characteristics of rigid pile composite foundation with cushion, the calculation formula for the bearing capacity of the auger bored cast with pressure concrete pile composite foundation on soft ground is put forward. |
