In the context of sustainable development, there is a growing interest in mapping soil characteristics and land use, in particular to evaluate threats to soil quality. Fast non-invasive geophysical surveys have been used to estimate the areal distribution ...
Particle aggregation is a commonly observed phenomenon in many types of soils, such as natural clays and agricultural soils. These soils contain porous aggregates, often separated by large, interaggregate pores. Two levels of intra- and interaggregate poro ...
Heavy rainfall can lead to shallow slips in slopes that are initially in a state of partial water saturation. Multiphysics numerical modelling approaches taking into account the involved physical key processes in variably saturated soils during rainfall ev ...

The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...
Natural and agricultural soils usually possess an aggregated structure; in the sense that they are composed of aggregates and large inter-aggregate pores. Under the natural condition, these soils are usually unsaturated and the large pores are easily drain ...
The trend in modern unsaturated soil mechanics is to enhance the physical understanding of the soil water retention properties. It is agreed that the retention characteristics depend on the state of compaction and are related to the deformability of the me ...
Presented here is a numerical investigation of the influence of non-uniform soil conditions on a prototype concrete bridge with three bents (four span) where soil beneath bridge bents are varied between stiff sands and soft clay. A series of high-fidelity ...
Despite the recent experimental studies of soil structure, a comprehensive understanding of the macroscopic response of a soil in relation to its structure has not yet been achieved. This lack of understanding reveals the need for further assessments of so ...
In this paper, a theoretical and experimental investigation of the effect of temperature on water retention phenomena in deformable soils is presented. A general law expressing the change in suction with water content, temperature and void ratio is propose ...
This study proposes a new advanced algorithm for determining material parameters based on in situ tests. In situ testing gives an opportunity to perform soil characterization in natural stress conditions on a representative soil mass. Most field techniques ...
