This paper presents a study of liquefaction-induced lateral ground displacements along the coast of Izmit Bay during the 1999 Kocaeli (Izmit)-Turkey earthquake. The paper discusses: (1) observed ground displacements after the earthquake, (2) the results of field investigations by means of borings and in situ index tests, including standard penetration tests, static cone penetration tests, and piezocone tests, (3) analyses of expected lateral displacements using two empirical models and one semiempirical model, and (4) comparisons between observed and calculated lateral ground movements. The three models provide inconsistent predictions of observed lateral ground displacements, with one method overpredicting and two methods both overpredicting and underpredicting observed lateral ground displacements by large amounts. Thus, it appears that there is a need for improved engineering tools for prediction of small to moderately significant lateral ground displacements (lateral displacements of approximately 0.1–2.5 m) at soil sites with similar ground characteristics to the case history sites presented herein.

Zero-Displacement Lateral Spreads, 1999 Kocaeli, Turkey, Earthquake Youd, T. Leslie; Deden, Daniel W.; Bray, Jonathan D.; Sancio, Rodolfo; Çetin, Kemal Önder; Gerber, Travis M. (American Society of Civil Engineers (ASCE), 2009-01-01) Three potential lateral spreads exhibited negligible displacements during the 1999 Kocaeli, Turkey Earthquake (M(w)=7.5) even though they were located within 7 km of the fault rupture. These spreads are analyzed to verify and augment current procedures for predicting liquefaction resistance and lateral spread displacement. The sites include Cark Canal and Cumhuriyet Avenue in Adapazari, underlain by fine-grained sediment, and Degirmendere Nose adjacent to Izmit Bay, a steeply sloping area underlain by moder...
Geotechnical rock-mass evaluation of the Anamur dam site, Turkey Ozsan, A; Karpuz, Celal (Elsevier BV, 1996-03-01) This paper describes a feasibility-level geotechnical evaluation carried out at Anamur dam site, in terms of stability analysis of dam foundation, excavation slopes and a diversion tunnel. The proposed Anamur dam will be built across the Anamur river on the Alanya metamorphic series which consists of phyllite, schist and slate units at the site. Geotechnical investigations included drilling for core, pumping tests, sampling for laboratory testing, and a detailed discontinuity survey.
Liquefaction-induced ground deformations at Hotel Sapanca during Kocaeli (Izmit),Turkey earthquake Çetin, Kemal Önder; Seed, RB; Bray, JD; Sancio, R; Lettis, W; Yimaz, MT; Durgunoglu, HT (Elsevier BV, 2002-10-01) This paper presents a study of liquefaction-induced ground deformations at the Hotel Sapanca site during the 1999 Kocaeli (Izmit)-T Turkey earthquake. The paper discusses: (1) observed ground deformations and displacements after the earthquake, (2) the results of field investigations by means of borings and in situ index tests including standard penetration tests (SPT), static cone penetration tests (CPT) and piezocone (CPTU) tests, (3) analyses of observed ground settlements and lateral deformations by a s...
Empirical attenuation equations for vertical ground motion in Turkey Kalkan, E; Gulkan, P (SAGE Publications, 2004-08-01) In the aftermath of two destructive urban earthquakes in 1999 in Turkey, empirical models of strong motion attenuation relationships that have been previously developed for North American and European earthquakes have been utilized in a number of national seismic hazard studies.. However, comparison of empirical evidence and estimates present significant differences. For that reason, a data set created from a suite of 100 vertical strong ground motion records from 47 national earthquakes that occurred betwe...
Performance of seismic-isolated bridges in relation to near-fault ground-motion and isolator characteristics Dicleli, Murat (SAGE Publications, 2006-11-01) This paper investigates the performance of seismic-Isolated bridges (SIBs) subjected to near-fault (NF) earthquakes with forward rupture directivity effect (FRDE) in relation to the isolator, substructure, and NF earthquake properties, and examines some critical design clauses in AASHTO's Guide Specifications for Seismic Isolation Design. It is found that the SIB response is a function of the number of velocity pulses, magnitude of the NF ground motion, and distance from the fault. Particularly, a reasonabl...
