Back-analysis of bi-directional pile load tests of drilled shaft socketed in weak rock

Back-analyses using the finite-element method were undertaken to evaluate the performance of three bi-directional pile load-tested (BPLT) drilled shafts socketed into weak rock (sandstone) for a cable-stayed bridge structure. The hardening soil (HS) model was employed to define the stress–strain relationships of the so...
