Present investigation intends to examine the mechanical behaviour of compacted coal fly ash – carbide lime mixes to assess their potential use as a sub-base/base material for low volume roads. This study plans to compute the impact of carbide lime content and dry density on the properties (durability and strength) of compacted coal fl...
View ArticleLithology volumetric estimation was performed from samples of drills using three-dimensional geostatistical techniques. Monte Carlo simulations were performed to test the accuracy and influencing factors. Next, procedures were applied to a case study related to the environment. The simulation results show that estimates obtained via block Kriging can be...
View ArticleIn this paper, two new state variables are included in a conventional elastoplastic model, Modified Cam-clay, to incorporate the influence of pore size distribution changes in the mechanical behavior of unsaturated soils. The first state variable allows capturing the influence of large pore changes in the mechanical behavior, and is controlled by an evo...
View ArticleThis paper presents the results of a field investigation into pile setup in overconsolidated clay soil that was conducted during a period of almost seven years, at Guabirotuba Geological Formation, south of Brazil, where the experimentation site of the Federal University of Paraná is located. One driven precast prestressed concrete pile was s...
