The dynamic behavior of soft soils constitutes a critical area of geotechnical engineering and earthquake engineering. The aim of the study is to investigate the effect of different approaches in predicting the surface response of dynamic behavior in soft soils. The change of soil properties under dynamic loads is investigated by finite element models. The dynamic behavior of soft soil samples modeled as one dimensional (1D) and two dimensional (2D) was investigated using PLAXIS and DEEPSOIL software. To reveal the effects of 1D and 2D approaches on the surface response, various parameters were analyzed in detail. The variations in the surface response with the changes in soil properties was obtained and it was seen that the soil properties is a critical factor in the accurate prediction of the surface response. The results also showed that the model dimension should be taken into account in predicting the dynamic behavior in soft soils and that this effect is important both in modeling approaches and in engineering solutions in the field. These findings provide important data that will contribute to the safer and more accurate implementations of geotechnical designs.

Öz

Yumuşak zeminlerin dinamik davranışı, geoteknik mühendisliği ve deprem mühendisliği açısından kritik bir çalışma alanı oluşturmaktadır. Bu çalışma, yumuşak zeminlerde dinamik davranışın yüzey tepkisinin tahmin edilmesinde boyut etkisinin rolünü araştırmayı amaçlamaktadır. Dinamik yükler altında zemin özelliklerinin değişimi hem sonlu elemanlar yöntemi ile modellemeler hem de deneysel yaklaşımlar ile ele alınmaktadır. Sonlu eleman analizleri ve bilgisayar destekli mühendislik yöntemleri, günümüz araştırma ve geliştirme projelerinde kritik bir rol üstlenmektedir. Araştırma kapsamında, 1 boyutlu ve 2 boyutlu olarak modellenen yumuşak zemin örneklerinin dinamik davranışı PLAXIS ve DEEPSOIL programları kullanılarak incelenmiştir. Boyut etkisinin yüzey tepkisi üzerindeki etkilerini ortaya koyabilmek için çeşitli parametreler detaylı olarak analiz edilmiştir. Elde edilen bulgular, zemin özelliklerinin değişiminin yüzey tepkisinde ne tür değişimler yaptığını ve bu değişimin yüzey tepkisinin doğru tahmininde kritik bir faktör olduğunu göstermiştir. Sonuçlar, boyut etkisinin yumuşak zeminlerde dinamik davranışın öngörülmesinde dikkate alınması gerektiğini ve bu etkinin hem modelleme yaklaşımlarında hem de sahada uygulanacak mühendislik çözümlerinde önem arz ettiğini ortaya koymuştur. Bu bulgular, geoteknik tasarımların daha güvenli ve doğru bir şekilde gerçekleştirilmesine katkı sağlayacak önemli veriler sunmaktadır.
