In this paper, the free strain radial consolidation theory incorporating the changes of compressibility and permeability of the soil with the change in effective stress via time dependent surcharge preloading is presented. In contrast to the conventional analysis, the current study highlights the nonlinear characteristics of the soil during the consolidation process. A comparison of the nonline...

piping sometimes is occurred due to seepage of water in hydraulic structures. the continuty of this phenomenon decreases the safety or caused the failure of a structure. in this work, experimental tests were carried out on statically compacted natural and randomly reinforced silt sandy soil samples. the randomly reinforced samples were prepared with different lengths and percentages of an artif...

A simple technique is proposed in this paper for estimating the coefficient of permeability an unsaturated soil based on physical properties soils that include grain size analysis, degree saturation or water content, and porosity soil. The method requires soil-water characteristic curve prediction as most conventional methods. procedure to define hydraulic conductivity function from which measu...

The common presence of the radioactive nuclides in the environment cause that the whole population are exposed to radiation. The dose that is annually received by Polish population from natural sources of radiation is about 2.4 mSv per year [1]. According to the UNSCEAR 2000 Report [2], radon is the greatest contributor of exposure to natural radiation for humans. Soil and the rocks on which th...

In this study, the smear zone due to vertical drain installation is studied using a large, in situ sample to capture the realistic characteristics of the smear zone in relation to the in situ soil structure. The smear zone extent for Bulli clay (New South Wales, Australia) is quantified on the basis of normalised permeability and the reduction in the water content prior to consolidation. The pe...
