Ultimate Bearing Capacity Tests on Sand with Clay Layer
Publisher: American Society of Civil Engineers
Abstract: Loading tests on nonuniform sand beds with a clay layer are carried out to make the effect of an interstratified weak layer on the ultimate bearing capacity clear. The tests are done under plane strain conditions using a ...
Rolling Resistance at Contacts in Simulation of Shear Band Development by DEM
Publisher: American Society of Civil Engineers
Abstract: To simulate numerically the microstructure of shear bands, the distinct element method was modified such that the effect of rolling resistance at contacts could be taken into account. To this end, the relative movement by ...
Microstructural Interpretation on Reliquefaction of Saturated Granular Soils under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: It is well known that the resistance to liquefaction of a saturated sand decreases sharply when it has been presheared, either cyclically or quasi statically, beyond a threshold value. The possible mechanism is discussed ...
Simulation of Upward Seepage Flow in a Single Column of Spheres Using Discrete-Element Method with Fluid-Particle Interaction
Publisher: American Society of Civil Engineers
Abstract: The interaction between soil particles and pore water makes the behavior of saturated and unsaturated soil complex. In this note, upward seepage flow through a granular material was idealized using a one-column particle ...
