Abstract:

 Explosive materials and blasting technology are inevitably employed in the fragmentation of rock masses to make them transportable. Blasting technology, widely used in mining activities, is also frequently utilized in construction projects for foundation excavation and site leveling. The proximity of construction projects to residential areas often creates challenges regarding the environmental impacts of blasting operations. In particular, the effects of blast-induced vibrations on structures near the project site should be evaluated using vibration propagation equations, by the vibration level limits permitted by the Environmental Noise Control Regulation. For this purpose, blast-induced vibration measurements were conducted at a construction project site in Bodrum to assess the impact of blasting activities on nearby buildings, and a site-specific vibration propagation equation was established. Using the propagation equation obtained specifically for the site, vibration velocity predictions were made and comparatively presented based on the equations provided for construction site blasting in the Blasting Designs and Environmental Effects of Blasting Guide published by the Ministry of Environment, Urbanization, and Climate Change. The studys results indicate that using the prediction models provided in the guide for environmental impact assessment at construction sites is inappropriate. Instead, conducting on-site vibration measurements to derive a site-specific vibration propagation equation is essential to prevent potential damage to nearby structures.

 Günümüzde kaya kütlelerinin parçalanarak taşınabilir duruma getirilmesinde mekanik kazının uzun süreler alması bu sebeple ekonomik olmaması, maruz kalınan gürültü süresinin artması, sert kayaçlarda kırıcı makinalarıın parçalama başarısının düşük olması gibi sebeplerden dolayı patlayıcı maddeler ve patlatma teknolojisi kaçınılmaz olarak uygulanmaktadır. Madencilik faaliyetlerinde yaygın olarak kullanılan patlatma teknolojisi aynı zamanda inşaat projelerinde temel kazısı ve alan düzeltme amacıyla sıklıkla kullanılmaktadır. İnşaat projelerinin çoğunlukla yerleşim yerlerine yakın alanlarda olması patlatmalı kazı çalışmalarının çevresel etkileri açısından problem yaratabilmektedir. Özellikle patlatma kaynaklı titreşimlerin Çevresel Gürültü Kontrol Yönetmeliğinde izin verilen titreşim seviyesi limit değerlerine göre, proje alanına yakın yapılar üzerindeki etkisi titreşim yayılım denklemleri kullanılarak değerlendirilmelidir. Bu amaçla Muğla ili, Bodrum ilçesinde bir inşaat projesi alanında gerçekleştirilen patlatmalı kazı çalışmalarının çevre binalara ekisini değerlendirebilmek amacıyla titreşim ölçümleri gerçekleştirilerek titreşim yayılma eşitliği oluşturulmuştur. Saha özelinde elde edilen yayılım eşitliği ile Çevre Şehircilik ve İlkim Değişikliği Bakanlığı tarafından yayımlanan Patlatma Tasarımları ve Patlatma Kaynaklı Çevresel Etkiler Kılavuzunda patlatma türü olarak inşaat alanı için verilen eşitlikler kullanılarak titreşim hızı tahminleri yapılmış ve karşılaştırmalı olarak sunulmuştur. Yapılan çalışma sonucunda inşaat alanlarında kılavuzda verilen tahmin modellerinin kullanılarak çevresel etki değerlendirmesi yapılmasının uygun olmadığı, mutlaka sahada titreşim ölçümleri gerçekleştirilerek saha özelinde bir titreşim yayılım eşitliği elde edilmesinin çevre yapılara olası bir zararı önlemek için gerekli olduğu görülmüştür.
