“…al. [8] performed field test with the use of 7 separate footing diameters up to 0.9 m, in addition to 3 different thickness of the granular fill layers. As the tests have ended, the load-settlement curves were plotted, while the bearing capacity that is related to the circular shallow footings which are supported via compacted granular fill layers over a natural clay soil has been predicted.…”

“…Results for the 2-layered soil sand on clay profile will be compared with the ones of Hanna and Meyerhof[7] and it has been noticed that through the increase of the thickness of the top layer, the discrepancy rises via overestimating Huang's approach.Ornek, et. al [8]. performed field test with the use of 7 separate footing diameters up to 0.9 m, in addition to 3 different thickness of the granular fill layers.…”

The bearing capacity of layered soil studies was carried out with various approaches such as experimental, theoretical, numerical, and combination of them. This work is focused on the settlement and bearing capacity of shallow foundations subjected to the vertical load placed on the surface of layered soils. The experimental part was performed by manufacturing soil cubic container (570 mm x 570 mm x 570 mm). A model square footing of width 60 mm was placed at the surface of the soil bed. The relative density of sand was constant at 60%, and the clay was prepared with a density of 19.2 (kN/m3) and water content of 14.6%. PLAXIS 3D FEM was used to simulate the experimental tests and performing a parametric study. The results showed that there was a good agreement between experimental work and corresponding numerical results. The value of the bearing capacity was obtained from load-settlement curve. The bearing capacity of layered soil showed higher value for footing resting on clay over sand soil. It was found that an increase in the ultimate bearing capacity regarding the clay over sand with increasing in first layer thickness ratio; while, a decrease has been indicated for the sand over clay. The critical depth was found at H = (2-3m), and the failure pattern was not unique for layered soil.

“…Even though, health and safety regulations are currently active in many countries including Europe, organizations are ineffective to protect their workers' health and safety (Verra, Benzerga, Jiao, & Ruggeri, 2018). Electrical plate compactor (Misir & Laman, 2017), roller operations, vibrator operations and hand compactor operations are some of the usage areas for the vibration for the compaction of construction materials. And construction workers are often forced to work for a long time using their physical strength to the fullest.…”

Öz Titreşimler yani; ses dalgaları, belirli bir süre içinde belirli sayıda tekrar eden dalgalardır. Ses dalgalarından farkı, sesin hava yoluyla iletilmesidir, titreşim ise vücudun katı kısımlarını kullanır. Titreşimler, operatörlerin el ve kollarına ve hatta tüm yapılarına bina operasyonlarında kullanılan makine ve ekipmanlardan geçer. Titreşimler birçok rahatsızlığa neden olur. Özellikle inşaat sektöründe, yüksek frekanslı titreşim yayıcı makina ve ekipmanlarda çalışan işçilerde ciddi sağlık sorunları gözlenmektedir. Bu sağlık sorunlarından en yaygın olanı orta ve uzun vadede ciddi mesleki ve bazı sağlık sorunlarına neden olan titreşimli bir sendromdur. Titreşim sendromu hastaları özellikle inşaat işlerinde fonksiyonel, sosyal ve psikolojik sakatlık yaşarlar. Bu nedenle, bu mesleklerin sigortaları ve amortismanları diğer çalışanlardan farklı olmalıdır. Bu çalışmada inşaat işçilerinin titreşim sendromu risk sınıflamaları yapılmıştır. Sıkı kavanoz açma zorluğu, el kavrama zayıflığı ve parmak rengi değişiklikleri çalışanların genel sorunları arasında öne çıkmaktadır. Ankete göre parmak soğukluğu ve parmak uyuşukluğu daha az ortaya çıkmaktadır. Bu sonuca göre gerekli önlemler ve yasal mevzuat önerileri sunuldu. Titreşime maruz kalan inşaat işçilerinin emeklilik yaşı için Taguchi metoduna dayalı bir optimizasyon yapıldı. İnşaat işçilerinin çalışma sürelerinin analiz sonuçlarına göre yeniden incelenmesi gerektiği sonucuna varılmıştır. İlgili mevzuat, her meslek için önerilen emeklilik yaşı uyarınca güncel tutulabilir.
