Three case studies involving the use of numerical models are presented in this paper. First, a comparison of FE modelling of a deep excavation is made using 2-D finite element software, SAGE-CRISP and PLAXIS. In the second study, benchmarking is made between results obtained from 2-D FE modelling using PLAXIS and well-established 3-D centrifuge studies for the case of an existing single pile an...

Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid cyclic loading. Liquefaction and related phenomena have been responsible for huge amounts of damage in historical earthquakes around the world. Modeling of soil behavior is the main step in soil liquefaction prediction process. Nowadays, several constitutive models for sand...

Abstract The dynamic response of the retaining structures is a complex issue, and major challenge in their design, especially under seismic loading conditions. So reliable efficient solution following computational approach, closer to reality, required obtain satisfactory results. Hence, this study came clarify effectiveness PLAXIS 3D program predicting performance, accuracy, reliability walls....

This study aims to identify the impacts of one-strut failure (OSF) during deep excavation in loose medium-dense sand with respect strut loads and wall deflections. The finite element software PLAXIS was used carry out both 2D 3D analyses. In addition, as two-dimensional (2D) analysis is commonly applied engineering practice due limited budget time, reasonable transferring results obtained using...

This study aims to demonstrate the effects of geogrid reinforcement on bearing capacity strip footing under eccentric loading. Numerical analysis using finite element program called (PLAXIS 2D Professional v.8.2) are presented. The effect each depth ratio topmost layer (u/B), vertical distance between consecutive layers (h/B), number (N), and effective (d/B) were studied, where (B) is width. Al...

Kondisi tanah dasar yang lunak sering menjadi permasalahan pada konstruksi pembangunan suatu bangunan, sehingga apabila tidak dilakukan perbaikan terlebih dahulu, maka akan mengalami penurunan relatif besar. Dalam penelitian ini menggunakan metode deep mixing dimodelkan sebagai plat untuk meningkatkan stabilitas tanah. Berdasarkan laporan investigasi tanah, lokasi di kota Banjarmasin termasuk j...

One of the efficient techniques to improve the behavior of the paved road under traffic loads is implementing the geosynthetic material in the sub-base or the soil under the road. In the past years, many researches have been done about this topic, but the study on the effect of soil/load conditions on the performance of the rehabilitated paved road by geogrid in order to investigate the effecti...

Taş kolon, yumuşak zeminin taşıma kapasitesini artırmak, zemin konsolidasyonunu hızlandırmak ve oturmasını azaltmak için kullanılan etkili bir iyileştirme yöntemidir. Bu çalışmada, literatürde geçmiş laboratuvar çalışmasından alınan doğrulanmış sayısal model parametreleri kullanılarak taş kolonun zamana bağlı davranışını değerlendirmek dizi çalışma yapılmıştır. kolon ile iyileştirilmiş birim hü...
