“…Waves that travel from the impact point to the recording point will attenuate accordingly to a linear relationship with distance. This is called "geometrical" attenuation and it is expressed by the following equation [14]: v b = v a (r a /r b )e ␣(ra-rb) where: v a = peak amplitude of surface vibration (m/s) at point a, at a distance r a (m) from the source; v b = peak amplitude of surface vibration (m/s) at point b, at a distance r b (r b > r a , m) from the source; In our case, we assumed ␣ = 1, so that any deviation from this simple rule, if the excitation is kept constant, may be related to a defective structural link. In this case the analysis is conducted exclusively in the time domain and the main difficulty resides in the flexibility of the whole vault, that can mask dangerous situations, so that a close scrutiny of data was required.…”

“…Excessive vibrations can also result in nuisance to local communities, interference with sensitive equipment/facilities and a decrease in the serviceability, durability or structural integrity of structures (Amick and Gendreau, 2000;BSI, 2014b;ISO, 2010).…”

Civil infrastructure projects such as bridges can have a major impact on many of the issues relevant to sustainability and it is therefore important that civil and structural engineers have methods at their disposal that will help them deliver sustainable designs. This paper describes a new model for appraising the sustainability of bridges. The indictors used to assess sustainability are climate change, resource use, waste, biodiversity and heritage, noise, dust, vibration, aesthetics, employment and businesses, construction costs, maintenance costs and user delay costs. The paper describes the aim of each indicator and provides details of the methods of measurement. The paper also presents the results of a case study on the appraisal of three alternative designs of an over-bridge for a dual twolane motorway to discover which option is the most sustainable. Details of the key input parameters are provided.The way in which individual impacts are combined to produce an overall sustainability score for a given structure is highlighted. The paper concludes with a discussion on interpreting the results and ways of further improving the sustainability of the selected design.

“…Öncelikle yazarların daha önceki çalışmaları ile kullanılan sayısal model, zeminin serbest yüzeyindeki düşey yerdeğiştirmelerin (u y ) zamana bağlı değişimleri incelenerek karşılaştırılmış [30] ve nümerik analizlerde kullanılacak sonlu eleman modelinin genişliği B=200m ve derinliği ise H=50m olacak şekilde belirlenmiştir. Ayrıca, Modelin doğrulanması işlemi Amick ve Gendreau [31] tarafından geliştirilen Bornitz'in iki nokta arasındaki enerji azalımı ile ilgili olarak sunmuş olduğu teorik formülasyon kullanılarak da gerçekleştirilmiştir. Bu teoriye göre, geometrik ve malzeme sönümünün yerdeğiştirme genliklerinde neden olduğu azalım aşağıdaki formülasyon kullanılarak ifade edilmektedir.…”

ÖZETHızlı 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 USING ARTIFICIAL BEDROCK IN MINIMIZING THE EFFECTS OF VIBRATION INDUCED BY HIGH SPEED TRAINS ON THE NEARBY STRUCTURES IN ALLUVIAL SOILS ABSTRACTAn artificial bedrock as wave impeding barrier can be used in practical civil engineering applications as isolation measures to protect structures from strong vibrations transmitted through soft ground nearby high-speed railway track. This study focuses on mitigation of the effects of high speed trains inducued vibrations on the strucutres which are located near the track lines by installing wave impeding barriers. Extensive parametric studies on the screening performance of wave impeding barrier have been done for both active and passive isolation cases.Keywords: Artificial bedrock, high speed train, wave propagation in alluvial soils, finite element method, nonlinear behaviour of soil
