Yüksek Hız Trenlerinin Çevre Binalardaki Titreşim Etkilerinin Azaltılması

Öz

Bu çalışmanın öncelikli hedefi hızlı tren trafiğinin ürettiği zemin titreşimlerini, yapı-zemin etkileşiminin de hesaba katıldığı bir dalga yayılım problemi olarak değerlendirip, ayrık sayısal çözüm yöntemlerinden yararlanarak sistemin matematik modelini geliştirerek incelemek ve dalga bariyerlerinin yerleştirilmesi ile çevre yapılardaki etkilerinin azaltılmasına ilişkin çözümler sunmaktır. Dalga bariyerinin yalıtım performansı tesis edileceği yere ve iç dolgu malzemesine göre kapsamlı parametrik çalışmalar yürütülerek araştırılmıştır.

Anahtar Kelimeler

• Düşey dalga bariyeri, sonlu elemanlar, enerji yutucu sınırlar, Mohr-Coulomb davranış modeli
