The deformation characteristics of deep mixed columns in soft clayey soils : a model study
Şengör, Mahmut Yavuz; Ergun, Mehmet Ufuk; Department of Civil Engineering (2011)
Deep Mixing involves the introduction of cementitious or specially formulated solutions directly into the ground through the use of purpose built blending injection augers. The system is mainly designed to increase strength and reduce compressibility of treated soil. In the first stage of the research effective mixture ratios and mixture types of stabilizing agents were investigated for soft clays (CL form Eymir lake and kaolinite) by means of unconfined compression (UC) tests on stabilized soils. The uncon...
Comparison of 2D and 3D finite element models of tunnel advance in soft ground: a case study on Bolu tunnels
Üçer, Serkan; Bakır, Bahadır Sadık; Department of Civil Engineering (2006)
The Bolu Tunnels lie along Trans European Motorway (TEM) which is connecting Eastern Europe with the Middle East. The tunnels are approximately 3.0 km long, 40 m apart and have excavated cross sections more than 200 m2. In construction, New Austrian Tunneling Method (NATM) was used in soft ground. Due to the challenging ground conditions, many problems have been encountered during tunnelling. To solve these problems special construction techniques were adapted. To simulate and demonstrate the effectiveness ...
Comparison of measured and predicted consolidation settlements in soft ground /
Ergin, Serhan; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2014)
Accurate prediction of consolidation settlement of soft clay and silt deposits has always been a topic of interest for geotechnical engineers. The objective of this study is to investigate the use of a few different computational tools for the realistic prediction of consolidation settlement in soft ground. During the literature review phase of this study, one well-documented case history of embankment constructed on soft ground with prefabricated vertical drains has been selected for further analyses. For ...
A Laboratory model study on settlement reduction effect of stone columns in soft clay
Sünnetçioğlu, Mehmet Emrah; Ergun, Mehmet Ufuk; Department of Civil Engineering (2012)
An experimental study was conducted in order to examine settlement reduction ratios of footing supported by both floating and end bearing type of stone columns. For the floating types, tests were done with varying column lengths of one and two widths of footing (L=B,2B). Tests were conducted in 200 mm* 200 mm* 200 mm cubic loading tanks. The reinforcement effect was achieved by the installation of four stone columns with 20 mm diameter under 70 mm* 70mm model footing. Parameters such as area replacement rat...
Formulation and implementation of a fractional order viscoelastic material model into finite element software and material model parameter identification using in-vivo indenter experiments for soft biological tissues
Demirci, Nagehan; Tönük, Ergin; Department of Mechanical Engineering (2012)
Soft biological tissue material models in the literature are frequently limited to integer order constitutive relations where the order of differentiation of stress and/or strain is integer-valued. However, it has been demonstrated that fractional calculus theory applied in soft tissue material model formulation yields more accurate and reliable soft tissue material models. In this study, firstly a fractional order (where the order of differentation of stress in the constitutive relation is non-integer-valu...
