Analysis of Soil Liquefaction using Numerical Modeling

Numerical modeling of liquefaction-induced lateral spreading

ABSTRACT: Liquefaction-induced lateral spreading of soils caused by strong shaking requires careful evaluation to be properly accounted for in geotechnical, and structural design of strategic infrastructure located in highly active seismic coastal regions. Although a large number of empirical and semiempirical models are available, there is still a lot of inconsistency in their predictions. In ...

Numerical simulation of liquefaction susceptibility of soil interacting by single pile

Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. As a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. In this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...

analysis of ruin probability for insurance companies using markov chain

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

Chapter 5 Liquefaction Analyses of Aggregate Pier Foundation System Using Numerical Modeling

The models that were analyzed using FLAC version 4.0 (FLAC, 2000) are shown on Figure 5.1. The models have different soil types: loose silty sand with 20% fines content (Figures 5.1a and 5.1b), soft clay (Figure 5.1c), and silt (Figure 5.1d). Hence, the determination of the parameters is different for each model. The following sections discuss the determination of the parameters used in the ana...
