Abstract
Full-scale lateral load tests on a group of bored and a group of driven pre cast piles were carried out as part of a research project for the proposed high-speed rail system in Taiwan. Standard penetration tests, cone penetrat ion tests (CPT), and Marchetti Dilatometer tests (DMT) were performed befor e the pile installation. The CPT and DMT were also conducted after pile ins tallation. Numerical analyses of the laterally loaded piles were conducted using p-y curves derived from preconstruction and postconstruction DMT and by applying the concept of p multipliers. Comparisons between preconstructi on and postconstruction CPT and DMT data and evaluation of the results of c omputations show that the installation of bored piles softened the surround ing soil, whereas the driven piles caused a densifying effect.
