this research is carried out to design and manufacturing of lathe vibration tool and their tests. firstly, one-dimensional vibration tool is designed and made of the bending vibration mode. one-dimensional vibration tool with half piezoelectric rings is considered to excite the bending mode of tool. structure of vibration tool is designed in abaqus software about 20 khz and then is made with re...

In this study, we performed one dimensional cylindrical sedimentation tests to investigate the impact of clay mineralogy, ionic concentration, valence on sedimentation, and self-consolidation behavior clay. The result at 1,000% 2,000% water content indicates that = showed higher coefficient initial settling velocity, faster initiation termination self-consolidation. Additionally, velocity decre...

The nonlinear flow law and soil boundaries greatly affect the dissipation process of consolidation. Thus, to study impact under impeded drainage boundaries, classical non-Darcian model described by non-Newtonian index was introduced. numerical solutions are derived in detail finite difference method (FDM) for one-dimensional (1-D) consolidation incorporating computer program is compiled. Then, ...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

Accurate predictions of the amount and the rate of long- term deformation of reinforced soils under an applied load are important key issue in geotechnical engineering, in which the deformation of soil develops with time at a state of constant effective stress. Since geosynthetic is generally considered creep sensitive therefore, evaluation of creep behavior of geosynthetic reinforced soil (GRS...

Sediments recovered from Ocean Drilling Program (ODP) holes undergo elastic rebound and physical expansion when recovered from great depths below the seabed (about 75 m). This expansion contributes to the artificial “growth” of the composite depth section (Hagelberg et al., 1992). Sediment elastic properties, derived from one-dimensional consolidation tests, are used to correct the expanded sed...
