Tüm mühendislik projeleri aynı zamanda bir risk yönetim uygulamasıdır. Bu nedenle mühendisler projeleri tasarlarken ve yönetirken bilinçli ya da bilinçsiz şekilde proje risklerini de yönetmek zorundadır. Beklenmeyen durumlarla karşılaşılabilecek mühendislik projelerinden biri de yeraltı mühendislik yapılarından biri olan tünel projeleridir. Bu çalışma yaygın bilinen tünel yapım teknikleri ile risk yönetim prensiplerini bir araya getirecek bir bakış açısı ortaya koymakta ve bir tünel projesinin uygulanması sırasında ortaya çıkabilecek olası sorunlara karşı önceden önlem alınmasına yardımcı olacak bir yöntem önermektedir. Bu çalışmanın amacı özellikle yeraltı mühendislik projelerinde risk yönetim ilke ve tekniklerinin kullanımı ile ilgili bir farkındalık yaratmaktır. Bu bağlamda tünel mühendislik tasarım ve kazı aşamaları senaryo yapılandırma modeli yöntemi ile değerlendirilmiş ve tünel projesinin tasarımdan yapım aşamasına kadar olan süreçlerde risk oluşturabilecek önemli belirsizlikler tanımlanmıştır.

Every engineering project inherently involves applications of risk management. For this reason engineers have to manage the risks consciously or unconsciously. Underground excavations are the projects that unexpected situations may occur mostly. This study combines common tunnel construction techniques and risk management principles and proposes a method that will help to take precautions against possible problems that may arise during the implementation of a tunnel project. In this context, tunnel engineering design and excavation phases were evaluated with the scenario structuring model and important uncertainties that could pose risks in the processes from the design to the construction phase of the tunnel project were defined. The aim of this study is to raise awareness about the use of risk management principles and techniques, especially in underground engineering projects.
