Rockfalls are one of the major hazards in hilly regions which can impose significant damages to the structures as well as human lives and property. Understanding the behavior of a rockfall along its trajectory is essential in order to design and implement protection measures for providing safe environment. Coefficient of restitution is one of the most important parameters for predicting a rockfall behavior. Back analysis is an effective tool in estimating the coefficient of restitution for a specific area. This study presents the analysis of rockfalls around the Mardin castle by probabilistic methods after estimating the real coefficient of restitution. Run out distance, bounce height, kinetic energy and translation velocity are studied in the area and accordingly barriers in 4 m height with capacities ranging from 3000 to 5000 KJ are suggested as protective measures.

Probabilistic seismic hazard assessment for earthquake induced landslides Balal, Onur; Gülerce, Zeynep; Department of Civil Engineering (2013) Earthquake-induced slope instability is one of the major sources of earthquake hazards in near fault regions. Simplified tools, such as Newmark’s Sliding Block (NSB) Analysis are widely used to represent the stability of a slope under earthquake shaking. The outcome of this analogy is the slope displacement where larger displacement values indicate higher seismic slope instability risk. Recent studies in the literature propose empirical models between the slope displacement and single or multiple ground mot...
Assessment of seismic hazard in the Erzincan (Turkey) region: construction of local velocity models and evaluation of potential ground motions Askan Gündoğan, Ayşegül; Karim Zadeh Naghshineh, Shaghayegh; Sisman, Fatma Nurten; Erkmen, Cenk (2015-01-01) The fundamental step in estimation of seismic damage and losses in urban areas is identification of regional potential seismic hazard. The accuracy of seismic analyses depends on the reliability of the local input parameters used in the corresponding hazard and loss models. This paper presents detailed seismic hazard analyses for an earthquake-prone region using locally derived source and site parameters. Main components of this study are construction of local seismic velocity models, probabilistic and dete...
Assessment of consolidation settlements in Karacabey soft clays: Estimated and monitored behaviour Çelik, Gözde; Topal, Tamer; Erol, Ahmet Orhan; Department of Geological Engineering (2020-9) Settlement of highway embankments constructed over clayey soft soils is a major problem encountered in maintaining highway facilities. Accurate estimation of consolidation settlement amounts and times has been a challenge for engineers in practice. In this study, field settlement measurements of 26 stations between 600 and 750 days of durations in Karacabey NC clays and comparison of these measured magnitudes of settlements with calculated settlements from oedometer tests are assessed. The correlation betwe...
Seismic Performance Evaluation of Concrete Gravity Dams by Using Pseudo Dynamic Testing and Simulations Aldemir, Alper; Binici, Barış (null; 2017-11-24) Dams are one of the mostimportantinfrastructure components servingfor water storage and energyproduction.Experimental studies on the seismic response of concrete gravity dams are scarce due to the complications regarding thelargescaleof dams and their interaction with the reservoir. This study presents the results of recent novel pseudo-dynamic dam tests (PSD) along with the nonlinear finite element simulations of the specimens. The test specimens were 1/75 scaled version of the highest ...
Assessment of tunnel induced deformation field through 3-dimensional numerical models (Necatibey subway station, Ankara, Turkey) Aktürk, Özgür; Doyuran, Vedat; Department of Geological Engineering (2010) In heavily settled areas, deformations induced by the tunnel excavation may cause serious damage to nearby structures. In this study it is aimed to model ground deformations induced by main tunnels and connection tunnels excavations as well as groundwater drainage. Therefore, it is necessary to study effective means of controlling tunnel induced deformations. The main parameters affecting the failure and deformation state of the soil around a circular underground opening are the physical characteristics of ...
