Yer Kabuğunun İçinde/Üstünde Güvenli Yapılar, Eurocode 7 ve Mühendislik

Abstract

Son zamanlarda mühendislik kavramı, ağırlıklı olarak bilgisayarlı uygulamalarla ve laboratuvar ortamlarıyla sunulurken, yerkabuğunun içinde/üstünde iş yapan yer mühendislerinin sorumlulukları çok fazla değişmemiştir. Bu mühendisler her zaman olduğu gibi günümüzde de duraylı (stabil) yapılar ve kazılar için yerle ilişkili kararlar vermek zorundadırlar. Yerkabuğunun farklı özellikleri ve yapısıyla ilgilenen yer mühendisleri konuyla bağlantılı olan; barajlar, tüneller, maden galerileri ve kazı arınları, açık maden ocakları, şevler, yapıların temelleri vb. konularda belirsizliklere rağmen duraylı yapılar için zorlu kararlar vermelidir. Son zamanlarda yerkabuğuyla ilgili konularda çalışan mühendisler: zemin, kaya, geoteknik, geomekanik, jeoloji, inşaat ve maden mühendisleri genel olarak “yer mühendisleri” olarak kategorize edilmektedir. Avrupa ülkeleri kademeli olarak EUR-ING başlığı altında “yer mühendisliği” spesifikasyonlarını tanımlamaktadır. Ürün kalitelerini kontrol eden, iş ve işçileri organize eden ve laboratuvarlarda testler yapan mühendislerin çoğunun fazla değişmeyen iş lokasyonu vardır. Bu durum her proje lokasyonu farklı olan yer mühendisleri için tamamen farklıdır. Bu çalışmada yer mühendisliği içeriğine kaya mühendisliğinin katkı konusu, Eurocode 7 kapsamındaki değerlendirmelerin ışığında ele alınarak incelenmiştir.

ENGINEERING REQUIRED TO HAVE SAFE STRUCTURES IN/ON THE EARTH CRUST AND EUROCODE 7

Abstract

While engineering has recently been presented in medias by computers and laboratory outfits, responsibilities of ground engineers who perform works in/on earth crust have not been changed at all. They have to supply stable spaces and structures for urban life in/on earth as they have been always required. Engineers dealing with earth for its properties, features, stabilities for different civil work circumstances like; dam, bridge, tunnel, mine gallery & stopes, pits, foundations of buildings etc. have their tough decisions under various uncertainties. They have recently been categorised as ground engineers including, soil and rock engineers, geotechnics, geomechanics, geologist, civil and mining engineers etc. subjects. Some European countries have gradually provided specifications to define ground engineering under EUR-ING qualifications. Engineers who have been controlling product qualities, organising works for employees, testing in laboratories have their work places which have not been changed regularly, as it is the case for ground engineers. Rock engineering, (concepts based mainly on rock mechanics in geology, mining and civil engineering) contributions to ground engineering have been worked here under Eurocode 7 applications and evaluations performed by engineers.
