| Abstract | ||
| Full scale field tests were performed on test piles installed based on a typical installation procedure of a precast bored piles, with various cement layer thickness and water-cement ratio of the cement slurry along the pile shaft. The results of the field test were compared to the test conducted on test pile following the installation procedure of driven piles. Simultaneously, large deformation finite element analysis was carried out to verify the effectiveness of precast bored piles under lateral loadings. Lateral displacement of the pile head was reduced as the thickness of the cement layer along the pile shaft increases, up to a certain thickness. Also, lower water-cement ratio also decreased the pile head displacement, but was found to have less effect compared to the cement layer thickness. Overall, the results show that the application of precast bored piles was found to be more effective in reducing the lateral displacement of the pile head under higher lateral loading. | ||
