Estimation of consolidation settlements caused by groundwater drainage at Ulus-Keçiören subway project

Altınbilek, M. Erdem
Prediction of ground settlements have always been a big challenge for the engineers that are responsible for the design of subway tunnel projects. Since ground settlement is a crucial concept directly affecting the successfulness of a project, it must be taken seriously and should be accurately estimated. Consolidation settlements in the close proximity of Ulus-Keçiören Subway project due to groundwater drainage is the focus of this study. In this sense, the necessary data about the project characteristics and the site conditions were collected thru project descriptions and the geotechnical investigations conducted at the project site. Utilizing the generated database analytical calculations were carried out to predict the settlements. Upon completion of this stage of analysis several of the locations were numerically modeled for further investigation. Numerical analysis was conducted at four sections by using Plaxis, to determine the amount of expected displacements and the resulting groundwater situation. Despite of the differences between these two methods the resulting settlement estimations displayed consistency.


Determination of Reliabffity Based New Load and Resistance Factors for Reinforced Concrete Structural Members
Firat, Fatih Kursat; Yücemen, Mehmet Semih (2014-07-01)
In this study, a procedure for the determination of new load and resistance factors for reinforced concrete structural members is proposed in view of the fact that the design practice in Turkey has changed after the occurrence of major earthquakes. The implementation of the procedure is carried out for the shear failure mode of reinforced concrete beams subjected to dead and live load combination. First, the statistical parameters for the quantification of uncertainties involved in the design variables are ...
Structural monitoring of andirap bridge for overload passage
Türer, Ahmet (2009-01-01)
Andirap bridge is located over Seyhan river passing a deep valley and has a big strategic importance since heavy loaded trucks carrying excavation and fill material from Kavsak Bendi hydroelectric power plant construction site have to use the bridge. Serious concerns were raised since Andirap bridge may not be adequately strong to carry about 250 trucks per day, each weighting more than 50 tons for the coming next two years. A preliminary visual and analytical evaluation of the bridge has leaded instrumente...
Numerical comparison of retaining system behavior for a deep excavation case with and without ground improvement
Maghsoudloo, Arash; Ahmadinaghadeh, Reza; Toker, Nabi Kartal (2012-11-02)
In the construction of deep excavations in urban areas, the safety of adjacent ground and structures becomes major concern for engineers. In soft clays, the main reason for occurrence of large deflections of soil support systems in excavations is instability of the excavation base. This paper will focus on analyzing and comparing design of an excavation with and without jet grout improvement applied to the excavation base by employing the finite-element code PLAXIS. A well-documented case study is analyzed,...
Assessing potential environmental impact and construction cost of reclaimed masonry walls
ÜÇER ERDURAN, DENİZ; Elias Özkan, Soofia Tahira; Ulybin, Aleksey (Springer Science and Business Media LLC, 2020-01-01)
Purpose The recovery of building materials and their reuse in new construction should be considered during the design stage of every new project. This study was conducted to quantify the potential environmental impacts and the economic feasibility of reusing waste material in new constructions with an applicable design solution. Methods Wall pieces reclaimed from the demolition debris of a historic building in St. Petersburg, Russia, were inspected for potential reuse, and their mechanical strengths were de...
Development of an IT-based tool for portfolio assessment and management for construction companies
Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019)
Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
