A Procedure to Prepare Sand–Clay Mixture Samples for Soil–Structure Interface Direct Shear Tests
نویسندگان
چکیده
A large number of experimental studies on sand–clay mixtures are well documented in the literature; however, preparation protocol is rarely clearly detailed or varies a lot according to authors. Variations technique obviously increases challenge comparing different test results. As consequence, sample for should be kept as constant possible ensure homogeneity and uniformity samples limit result variability. This paper develops procedure how prepare interface direct shear tests. Sand–clay prepared with Fontainebleau sand, kaolinite clay distilled water by S1 (sand–water–clay) protocol. The reconstituted specimens assessed measuring content density three slices from top bottom across specimens. repeatability checked oedometer can used preparing mixture tests investigate influence other effects (e.g., temperature) mechanical behavior soil–structure interface. It has demonstrated great performance good shape, compared traditional reconstitution techniques. With procedure, we obtain repeatable results well.

Numerical Studies of Shear Banding in Interface Shear Tests using a New Strain Calculation Method
Strain localization is closely associated with the stress-strain behavior of an interphase system subject to quasi-static direct interface shear, especially after peak state is reached. This behavior is important because it is closely related to deformations experienced by geotechnical composite structures. This paper presents a study using two dimensional DEM simulations on the strain localiza...
متن کاملInternal Structure Features of Asphalt Mixture for Field Samples
Asphalt mixture is heterogeneous in nature; therefore, macroscopic parameters alone cannot describe the mechanical behavior of the mixture. In recent years, the arrangement of the aggregate particles in terms of spatial and directional distributions, and contact points are considered as the internal structure of asphalt. The main purpose of this paper is to investigate the microstructural chara...

15 صفحه اولThree-Dimensional Discrete Element Simulations of Direct Shear Tests
Using discrete element methods, geotechnical engineers can create “virtual laboratories” to simulate conventional laboratory tests. In this study, three-dimensional DEM simulations of direct shear tests are coupled with equivalent physical tests on steel balls. The macro-scale response of simulations is compared with the physical test results to validate the discrete element model and to gain i...
