Ground failure in Adapazari, Turkey during the 1999 Kocaeli earthquake was severe. Hundreds of structures settled, slid, tilted, and collapsed due part to liquefaction ground softening. more severe adjacent under buildings. The soils that led building damage were generally low plasticity silts. In this paper, results a comprehensive investigation which included cone penetration test (CPT) profiles followed by borings with standard tests (SPTs) soil index tests, are presented. effects...
Abstract This study aims to evaluate the factors controlling sensitivity of fine-grained soils seismic stresses and revise criteria previously proposed by authors diagnose liquefaction. To this end, dynamic tests have been performed on artificial mixes as well natural from a wide area an earthquake devastated city (Adapazari) using two types testing. Studies led findings suggesting that gray between susceptible non-susceptible several investigators in past can now be dispensed with. Although...
This paper describes an attempt to develop a method define when granodiorite loses its properties as rock and transforms into soil material. The research program approached the problem from mechanistic point of view by comparing pore water pressures generated during isotropic compression with apparent—and micro—porosities, in terms newly proposed size distribution index well compressive strengths specimens tested. A site was selected for study where weathering is not accompanied production...
The authors of the aforementioned article, written in July 2004, respond to discussers' questions and comments concerning liquefaction bearing capacity. They believe that providing additional information on soil properties dynamic analyses from follow-up investigations will resolve differing opinions. closure discusses index shallow soils, silts clays, static strength, seismic Research found building movements damage were usually less severe at sites where buildings directly underlain by...

A settlement analysis has been carried out for several sectors of a rail station yard improved with prefabricated vertical drains (PVD) in Istanbul, Turkey, that exhibited prolonged consolidation beyond the predicted values certain treated zone. Final and End Primary (EOP) times have estimated theoretically as well using Asaoka graphical procedure. The compliance settlement-time curves in-situ measurements solution investigated. geotechnical model was developed finite element...
A logistic regression model has been developed for evaluation of soil liquefaction by the use cone penetration test (CPTu, PCPT) on data collected from Adapazarı, Turkey. The inputs are clean sand equivalent normalized tip resistance (qc1N,cs) and cyclic stress ratio corrected moment magnitude 7.5 earthquake (CSRM=7.5) that was experienced in 1999. Liquefaction probabilities (PL) obtained each district city which CPTu is available with proposed model. Average depth interval 0-6 m coordinates...
