Geotechnical Investigation of Hamzadere Dam

Öz

In this study, the geological characteristics of the Hamzadere Dam, designed as a homogeneous earth fill type, were examined. The geotechnical suitability of the fill material that will form the dam body was investigated through various tests. In this context, two locations were identified as material areas, and tests were conducted to determine the properties of the soils. Earth fill dams are significant engineering projects that require substantial investment. In such projects, preliminary investigations play a critical role in both economic efficiency and structural safety. Incorrect dam site selection and improperly designed clay cores during the construction phase can lead to numerous engineering problems. These issues can pose serious risks that may affect the construction process or the lifespan of the dam. Therefore, this study aims to demonstrate the importance of soil investigations in the construction of earth fill dams. This study addresses the engineering geology of the Hamzadere Dam, describes the experimental studies conducted on materials taken from the fill sites, and presents the results.

Hamzadere Barajının Geoteknik İncelemesi

Öz

Bu çalışmada, homojen toprak dolgu tipinde tasarlanan Hamzadere Barajı’nın jeolojik özellikleri incelenmiştir. Baraj gövdesini oluşturacak dolgu malzemesinin geoteknik açıdan uygunluğu çeşitli deneylerle araştırılmıştır. Bu kapsamda malzeme alanı olarak iki yer belirlenmiştir ve zeminlerin özelliklerini belirlemek amacıyla testler yapılmıştır. Toprak dolgu barajlar, önemli mühendislik projeleri olup büyük yatırım gerektiren yapılardır. Bu tür projelerde, ön incelemelerin yapılması, hem ekonomik verimlilik hem de yapı güvenliği açısından kritik bir rol oynamaktadır. Yanlış baraj yeri seçimi ve inşaat aşamasında uygun şekilde tasarlanmayan kil çekirdekleri, birçok mühendislik sorununa yol açabilir. Bu tür problemler, inşaat sürecinde veya barajın ömrü boyunca etkili olabilecek ciddi riskler oluşturabilmektedir. Bu yüzden yapılan bu çalışmayla, dolgu baraj inşasında zemin etütlerinin önemi gösterilmek istenmiştir. Bu çalışmayla Hamzadere Barajının mühendislik jeolojisine değinilmekte, dolgu sahalarından alınan malzemeler üzerinde yapılan deneysel çalışmalar anlatılmakta ve sonuçlan belirtilmektedir.
