Borehole tube sampling is a key process of geotechnical engineering. The paper presents numerical analyses smooth in clay using the particle finite-element method. soil described by conventional elasto-plastic constitutive model (Tresca plasticity and quasi-incompressible elastic law). sampler advanced several diameters into until steady state observed. solution for round-tipped clearly identif...

Tile drainage belongs to one of the most important meliorative measures in Czech Republic. It has been hypothesised that it may improve some soil properties which are influenced by groundwater and their water regime. In case meadows, used management method also influence properties. this study, different physical (particle bulk density, total porosity, maximum capillary capacity, minimum air re...

A series of cyclic direct simple shear tests are performed to investigate the liquefaction resistance sandy soils from Christchurch, New Zealand. The study focuses on combined effects soil density and fines content soils. Two sands, a non-plastic silt, their mixtures prepared at different contents tested two sets relative densities. Test specimens reconstituted using procedure for water sedimen...
