Fly ash is one of coal ashes resulted from power plants using coal to generate electricity. As a result of large utilization of coal, large volumes of coal ash produced as waste material. Direct use of these materials in construction projects, not only provides a promising solution to the disposal problem, but also as an alternative for structural fills material. High shear strength, low compre...

A continuum-based finite-element methodology is established for quantifying the stability of earthen embankments built on saturated soil deposits. Within the methodology the soil is treated as a fluid-solid porous medium, in which the soil skeleton’s constitutive behavior is modeled using a smooth elastoplastic cap model that features continuous coupling between deviatoric and volumetric plasti...

In December 1993, the river Meuse ooded and caused a damage of about 250 million Dutch guilders. This prompted the Dutch government to initiate a project to investigate and compare strategies that can reduce future losses due to ooding on the basis of several criteria, including some concerning uncertainties. To obtain decisions that reduce ood damage, one should account for the following uncer...

Three-dimensional finite element (FE) simulations were performed to further develop the Swedish design guidelines for geogrid-reinforced timber pile-supported embankments, also known as lightly piled embankments. Lightly embankments are constructed mainly in areas which typically have highly compressible soils, and method utilises untreated piles its key feature. The installed a triangular arra...
