“…It is useful to emphasize that the approximate approach proposed in this investigation is intended to be used for preliminary design of piles or as a check on the results from the detailed nonlinear analysis. The final evaluation of piles may be conducted by analysis of detailed pile-soil system using more advanced methods (e.g., Castelli and Maugeri 2009, Imancli et al 2009, El Naggar et al 2005, Allotey and el Naggar 2008, Chiou and Chen 2007.…”

Aabtract. This paper proposes an approximate procedure to estimate seismic displacement capacity − defined as yield displacement times the displacement ductility − of piles in marine oil terminals. It is shown that the displacement ductility of piles is relatively insensitive to most of the pile parameters within ranges typically applicable to most piles in marine oil terminals. Based on parametric studies, lower bound values of the displacement ductility of two types of piles commonly used in marine oil terminals − reinforced-concrete and hollow-steel − with either pin connection or full-moment-connection to the deck for two seismic design levels -Level 1 or Level 2 − and for two locations of the hinging in the pile − near the deck or below the ground − are proposed. The lower bound values of the displacement ductility are determined such that the material strain limits specified in the Marine Oil Terminal Engineering and Maintenance Standard (MOTEMS) are satisfied at each design level. The simplified procedure presented in this paper is intended to be used for preliminary design of piles or as a check on the results from the detailed nonlinear static pushover analysis procedure, with material strain control, specified in the MOTEMS.

“…However, for these soils, dissolved salt may induce wetting collapse in ground, leading to damages in infrastructures [5,6]. is kind of behaviours differs from both cohesive soils with good bonding between particles and coarse soils with better drainage [7][8][9][10]. us, the design of foundations involving the coarse-grained saline soil deserves urgent attentions for its bearing characteristics and ground treatment scheme.…”

Bearing capacity of belled pier foundation is critical in designing transmission lines in coarse saline soil region. This paper describes model test results on belled pier foundations. Axial uplift behaviours including failure modes, load-displacement curves, and ultimate uplift bearing capacity were discussed. The failure planes in four cases were obtained from pulled out cone-shaped bodies. An empirical equation was developed with a critical parameter of an uplift angle in design. Results indicate the range where the ground uplift shows circular extension at higher loads and the overall shear failure finally occurred. The load-displacement curves are primarily softening, and the uplift bearing capacity for coarse-grained saline soils (CSS) in the crystalline state increases at larger thickness, higher than that in dissolved state. Failure planes all exhibit approximately linear change from bottom to up. The angles of uplift for soils in crystalline and dissolved states can be taken as 34° and 18°, while 32° for the conventional for the sake of safety. Uplift behaviour of belled piers in CSS was modelled incorporating a practical interface model, with both failure planes and plastic range.
