Expansive clay found especially in the semi-arid or arid regions of the world is a problematic soil that causes much damage to the lightweight structures built by civil engineers. The Lime pile technique is one of the improvement techniques applied for the stabilization of the expansive clay subgrade layer of highway constructions. The achievement of this technique depends on lime diffusion into expansive clay which is affected by some parameters related to the lime pile such as the height of the lime pile, the surrounding area of all lime piles, area ratio, total lime pile volume, water percentages of the water-lime mixture, lignosulphonate added to the water-lime mixture and curing time. In this study, the heights of the lime piles are equal to 2/3 of active zone depth or full height of active zone depth, two different lime pile diameters which are 4.5 mm and 6.5 mm are selected and three different water percentages of lime-water mixtures are prepared as 0%, 18%, and 30%, respectively. Finally, sodium lignosulphonate (NaLS) and calcium lignosulphonate (CaLS) are added separately to the lime-water mixture. Thus, the lime pile parameters mentioned above have been investigated in this study and the most effective lime pile installation model has been developed. The Lime pile technique with NaLS and CaLS addition prevented the formation of ettringite minerals. The swell potentials of lime pile-treated soil with NaLS and CaLS addition were much lower than the swell potential of lime pile-treated soil. Calcium lignosulphonate is more effective than sodium lignosulphonate as calcium ions are more prone to ion exchange than sodium ions. The best lime pile model is obtained when the heights of the lime piles are equal to the full height of active zone depth and when the water content of the water- lime- CaLS mixture is equal to 30%.

The effect of group behavior on the pull-out capacity of soil nails in high plastic clay Akış, Ebru; Bakır, Bahadır Sadık; Department of Civil Engineering (2009) Soil nailing technique is widely used in stabilizing roadway and tunnel portal cut excavations. The key parameter in the design of soil nail systems is the pull-out capacity. The pull-out capacity of the soil nails can be estimated from the studies involving similar soil conditions or can be estimated from the empirical formulas. Field verification tests are performed before the construction stage in order to confirm the parameter chosen in the design of soil nailing system. It is reported in the literature...
Theoretical and practical aspects of compaction grouting Tuncdemir, Fatih (2007-01-01) Although not applied in Turkey, compaction grouting has been used widely in many parts of the world and especially in the USA in foundation engineering for reducing the void ratio of soils, relevelling of settled buildings, underpinning of footings and slabs, controlling settlements, and for mitigation of liquefaction potential of the soils in the last 10 to 15 years. In this study, a theoretical approach regarding compaction grouting has been presented, injection parameters and theological properties of th...
THE NONLINEAR RESPONSE OF UNREINFORCED MASONRY BUILDINGS TO EARTHQUAKE EXCITATIONS TANRIKULU, AK; MENGI, Y; MCNIVEN, HD (1992-11-01) The three-dimensional non-linear earthquake behaviour of unreinforced masonry buildings is studied by using a constitutive model established experimentally for burned-clay brick masonry wall panels. The parameter functions appearing in the constitutive model are modified so that they accommodate a wall panel made of a general masonry material. In the study it is assumed that the floors of the masonry building are reinforced concrete slabs which are infinitely rigid in their own planes and that the wall pane...
The effect of chemical admixtures and mineral additives on the properties of self-compacting mortars Sahmaran, M; Christianto, HA; Yaman, İsmail Özgür (2006-05-01) Mortar serves as the basis for the workability properties of self-compacting concrete (SCC) and these properties could be assessed by self-compacting mortars (SCM). In fact, assessing the properties of SCM is an integral part of SCC design. The objective of this study was to evaluate the effectiveness of various mineral additives and chemical admixtures in producing SCMs. For this purpose, four mineral additives (fly ash, brick powder, limestone powder, and kaolinite), three superplasticizers (SP), and two ...
A Semi-empirical method for estimation of maximum seismic shear strain in imperforated ground excited by vertically propagating shear waves Dehghanian, Kaveh; Yılmaz, Mustafa Tolga; Department of Engineering Sciences (2016) Seismic design of underground structures requires calculation of the deformation in surrounding geological formations. The seismic hazard on a site is usually expressed as a function of amplitude parameters of free-field motion. Therefore, simplified relations between depth and parameters of ground motion are necessary for preliminary designs. The objective of this study is to employ random vibration theory to develop a simple relationship between maximum shear strain (γmax), depth, and ground-motion intens...
