For appropriate safety assessment of the disposal of TRU waste, distribution coefficients (Kd) and gasification ratios of C labeled [1, 2-C] sodium acetate (C-NaOAc) were determed by batch sorption tests for 85 Japanese paddy soil samples. The soil studied were from four soil types: Andsol; Gley; Gray lowland; and Yellow. The range of Kd values for all soil samples was from 7.5 to 295.2 mL g , ...

The purpose of this paper is to review computational methods in structure-soil-structure interaction. As a result of globalization, buildings are located close to each other. This issue happens especially in big cities, making the study of structure-soil-structure interaction as an essential part of structural design process. The effect of soil medium, on which the building structure stands, es...

480 D use diff erent strategies to survive and fl ourish with erratically available water (Hamerlynck et al., 2002; Lombardini, 2006). Th e persistence of soil water within a particular depth range and its characteristic time scales of fl uctuation (Katul et al., 2007) help determine the resulting plant community. Th e depth to which infi ltration percolates and the degree to which water is ret...

Evaluation of soil-foundation-structure interaction (SFSI) effects on structural response is a challenging task because of the involved impact of uncertainties in system’s parameters and randomness in the input earthquake motion. In this paper, a rational method is utilized to elucidate these effects through the use of a rheological soil-foundation-structure model in a robust probabilistic simu...

This study presents observations of nonlinear soil behavior evidence at several KiK-net sites. First, we compare the site responses performed with 1) the recordings from the aftershocks and 2) the recordings from the main event of the 2011 Tohoku earthquake at four sites. Then, to understand the influence of soil parameters on nonlinear effects, we extend the results to the whole network. We co...

The present article shows the results of a study on the soil module of the STICS (Simulateur Multidisciplinaire des Cultures Standards, developed by INRA, France) crop model. Simulation models are often applied to regions where conditions are substantially different from the ones which the model was originally developed for and validated against. This was the reason to study the sensitivity of ...

This paper addresses the mechanical behavior of buried steel pipeline crossing subsidence strata. The investigation is based on numerical simulation of the nonlinear response of the pipeline-soil system through finite element method, considering large strain and displacement, inelastic material behavior of buried pipeline and the surrounding soil, as well as contact and friction on the pipeline...

Realistic physics-based simulation of vehicles on soft terrain has increasingly gained importance due to their broad application from operator training to mission planning and design. In this work we combine models from terramechanics and soil mechanics to represent the interaction of vehicles and their tools with a deformable terrain, allowing us to simulate a broad range of vehicles, includin...

There are various methods for stabilizing excavations in urban areas which one of them is the nailing method. Designing a nailing system and analyzing the performance of excavations is done by various software applications. One of these computer programs is PAXIS software which run based on the finite element method (FEM). In the present study, a numerical analysis of the performance of t...

Most agronomic situations involve a sequence of herbicide, fungicide, and insecticide application. On the other hand, use of pesticidal combinations has become a standard practice in the production of many agricultural crops. One of the most important processes influencing the behavior of a pesticide in the environment is its degradation in soil. It is known that due to several pesticide applic...
