Abstract This paper studies the two widely used material models for predicting dynamic behavior of soils, Ramberg-Osgood and Hadrin-Drnevich models. Resonant column torsional simple shear test results on dry sand were to calibrate evaluate model built in finite element software Midas GTS NX. Both are already implemented by software. study estimates ability efficiency both soil coupled with Masi...

The subway has become the main way for people to travel nowadays. saturated soft clay area a large population and construction is most extensively distributed. foundation will settle under dynamic load of train, which affect service life structural safety. To study settlement characteristics subway, three-dimensional finite element model was established based on software Midas GTS NX, normal de...

Abstract The dynamic properties of soil obtained from the torsional simple shear test (TOSS) are assumed to be uniform throughout specimen. For some exceptional soils, this may hold true, but for most majority soils that we examine, it is obviously not case, and level non-uniformity depends on conditions in which was formed. In paper, discuss a method modelling inherently non-uniform specimens ...

Kocaeli İli’ndeki bir trafo montaj-demontaj binasının bulunduğu arazide kapsamlı zemin etüdü yapılmış ve bu alanda sıvılaşma riskinin olduğu görülmüştür. Sıvılaşma riskini ortadan kaldırmak amacıyla jet grout kolonlar iyileştirme yöntemi olarak seçilmiştir. Tasarımı yapılan kolonların imalatından sonra kalkıp kalkmadığı, gerçekleştirilen analitik sayısal analizler ile incelenmiştir. Jet sıvılaş...

Abstract Liquefaction on bridges can cause structural failure due to loss of soil strength. The Showa Bridge that collapsed in 1964 Niigata earthquake was caused by buckling piles as the layer liquefied and friction losses. In addition, there a case Palu IV bridge collapse Indonesia during recent 2018 earthquake, which indicated have been affected earthquakes liquefaction. This study examines r...

Abstract The construction of shield tunnel will adversely affect the surrounding soil and is prone to safety accidents. This paper focuses on problem deformation induced by construction. Based theoretical mechanics Mindlin solution, caused frontal thrust, friction force formation loss linearly superimposed, accurate calculation formula derived in time space. Relying finite element software Mida...

The aim of the study is to determine further «green» operation a building - an object cultural heritage in technogenic conditions that formed 20-21 centuries, based on monitoring actual engineering and geological urban historical territory Voronezh. engineering-geological structures was carried out three stages. At first stage, reconnaissance survey identify surface forms manifestation modern p...
