Abstract
In this study, firstly, line drilling, smooth blasting and presplitting, which are known as controlled blasting techniques; are described in detail. Then, the applications of line drilling and smooth blasting in the T2 tunnel on the Tarsus Crossing-Gaziantep Motorway are given as an example. Fracturing beyond the excavation line and over breaking were minimised with a successful application of line drilling and smooth blasting in the T2 tunnel. As a result, less reinforcement and less concrete were needed and the cost was lowered
Özet
Bu çalışmada, önce kontrollü patlatma yöntemleri olarak bilinen hat delme, son-kesme ve ön-kesme detaylı olarak anlatılmıştır. Sonra Tarsus Ayrımı-Gaziantep Otoyolu T2 tünelinde son-kesme ve hat delme uygulamaları örnek olarak verilmiştir. T2 tünelinde başarılı bir son-kesme ve hat delme uygulaması ile kazı hattı dışındaki kayaçta çatlamalar ve aşın kazı en aza indirilmiştir. Bunun sonucunda tahkimat ve püskürtme beton kullanımı azaltılmış ve maliyet düşürülmüştür
