Hızlı demiryolu hattına yakın yapıları yumuşak zemin koşullarında taşınan kuvvetli titreşimlerden korumak için dalga bariyeri olarak yapay anakaya modeli inşaat mühendisliğinin pratik uygulamalarında kullanılmaktadır. Bu çalışmada, yüksek hızlı tren trafiğinin meydana getirdiği titreşimlerin demiryolu ağının çevresindeki binalarda oluşturduğu etkilerin azaltılması için dalga engelleyici bariyerlerin yerleştirilmesi araştırılmıştır. Yapay anakayanın aktif ve pasif yalıtım durumlarına göre performansını değerlendirebilmek için ayrıntılı parametrik çalışmalar gerçekleştirilmiştir.


Anahtar kelimeler


Yapay anakaya, yüksek hızlı tren, alüvyon zeminlerde dalga yayılımı, sonlu elemanlar metodu, doğrusal olmayan malzeme davranışı
