THE PERFORMANCE OF ROCK SOCKETTED PILES IN LOW STRENGTH SILTSTONE

Access to the channel island power station near darwin in the northern territory required the construction of two 500 m long bridges. Foundations for the bridges consist of large diameter rock socketted piles founded in subvertically bedded low strength siltstone. A test pile was constructed at each bridge site to assess the performance under axial (tension and compression) loading and lateral loading. Results from the channel island test indicated a backfigured rock modulus of twice the measured pressuremeter modulus from the compression test, and approximately equal values from the lateral test. Elizabeth river test results were less consistent with a backfigured modulus from the test up to ten times the measured pressuremeter modulus, interaction between the pile and reaction system affecting results.
