Abstract (sommario):

The use of tensile reinforcement to increase the tensile strength and shear strength of soils has lead to many new applications of reinforced soil. The use of such reinforcing in embankments and foundations over weak soils is one of the most recent applications of this technology. The studies conducted were concerned with the development of and application of analytical techniques to reinforced soil foundations and embankments over weak soils. A finite element computer program was modified for application to reinforced soil structures, including consolidation behavior of the foundation soil.

Abstract (sommario):

Thesis advisor: Alan Kafka<br>Heap leach flow patterns are governed by hydrogeological parameters including, soil properties, saturated and unsaturated hydraulic conductivity, initial degree of saturation, and the method of irrigation. Optimizing production during leaching cycles requires knowledge of the hydrogeological parameters of the leach heap, and their effect on flow behavior. This thesis research involved quantifying the flow rates of unsaturated homogenous soil profiles. Finite element numerical modeling has been utilized to simulate 1-dimensional unsaturated transient vertical flow.

Conventional constitutive models developed for saturated soils are inadequate when analysing problems involving unsaturated conditions. Although unsaturated constitutive models are available in the Imperial College Finite Element Program (ICFEP), there are aspects of unsaturated soil response that are not adequately simulated. The aim of the present thesis is to develop and implement numerical expressions describing the most relevant of these features and to apply them in combination with the existing ICFEP capabilities to boundary value problems involving unsaturated soils.

Abstract (sommario):

The behavior of porous media subjected to any arbitrary loading is a complex phenomenon due to the coupled nature of the problem. Proper understanding of this coupled behavior is essential in dealing with many of the geotechnical engineering problems. A very general three-dimensional formulation of such a coupled problem was first reported by Biot; however, a two-dimensional idealization of the theory is used here with extension to nonlinear material behavior. A finite element computer code is developed to analyze the response of coupled systems subjected to both static and dynamic excitations

During a volcanic eruption, the extrusion of lava onto surfaces destroys biological activity creating virgin land surfaces. Through time this new land will be subject to soil formation and colonisation under relatively similar climatic conditions and parent materials. Soils formed from volcanic deposits present a unique opportunity to study microbial community development. Soils at different developmental stages and differing in vegetation cover were selected from four locations on the slopes of Mount Etna, Sicily. Three main research objectives were determined in order to test the hypothesis

A study is undertaken to formulate and solve the equations governing the time dependent response of gassy soils.

The validity of such a program has been verified by comparing its results with closed form solutions. This program has then been applied to simulate the processes involved in depleting oil sand reservoirs in order to give some insight into the mechanism causing fluid flow and sand production.

Abstract (sommario):

A decade has passed since the development of the self-boring pressuremeter (SBPM). Even though the device has been recognized by the geotechnical engineering profession as having high promise for evaluating in-situ stress-strain behavior of soils, its use is limited. In large part, this is due to the fact that there are important unanswered questions about the SBPM test. One of the major issues concerns the influence of drainage in the soil as it is sheared. In clays, the test is assumed to be undrained, but there is no way to control this other than by the rate of loading and no method has be

First, a laboratory procedure, using backtitration, was developed for the measurement of the pH-dependent net surface charge. This method was tested on ten soil horizons from Gleysols and Podzols.

Frost heave describes the phenomenon whereby soil freezing causes upwards surface motion due to the action of capillary suction imbibing water from the unfrozen region below. The expansion of water on freezing is a small part of the overall surface heave and it is the flow of water towards the freezing front which is largely responsible for the uplift. In this thesis, we analyse a model of frost heave due to Miller (1972, 1978) which is referred to as `secondary frost heave'. Secondary frost heave is characterised by the existence of a `partially frozen zone', underlying the frozen soil, in wh

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR<br>No presente trabalho realizou-se a implementação de um programa de análise de estabilidade de encostas incluindo aspectos não convencionais tais como ruptura progressiva, anisotropia de resistência e considerações de não saturação do solo. O método generalizado das cunhas de Sarma 79 foi utilizado para consideração destes aspectos, tomando-o como base para o desenvolvimento desta nova ferramenta analítica, aplicável ao estudo da estabilidade de encostas em solos residuais não saturados. A simulação dos efeitos da ruptura

Abstract (sommario):

Cette thèse présente une analyse probabiliste de fondations superficielles reposant sur un sol variable spatialement et soumises à un chargement statique ou dynamique (sismique). Dans la première partie de cette thèse, le cas d'un chargement statique a été considéré. Dans cette partie, seule la variabilité spatiale du sol a été examinée et les propriétés du sol ont été modélisées par des champs aléatoires. Dans la littérature, la méthode de simulation de Monte-Carlo (MCS comme Monte Carlo Simulation) est généralement utilisée. Dans cette thèse, la méthodologie de développement par chaos polyno

Abstract (sommario):

Due to rapid urban developments and limited land in urban areas, it becomes necessary to construct underground transport infrastructure at much greater depths and quite often in poor ground congested with building structures and utilities. Deep excavation inevitably alter the ground conditions and induced ground deformations. This may cause damage to adjacent building structures and utilities. Therefore, understanding and being able to predict the performance of deep excavations to minimise movements induced damages is an important issue and a challenge to geotechnical engineers. Traditionally
