Design of foundations in earthquake prone areas needs special considerations. Shallow foundations may experience a reduction in bearing capacity and increase in settlement and tilt due to seismic loading. The reduction in bearing capacity depends on the nature and type of soil and ground acceleration parameters. In the case of piles, the soil-pile behavior under earthquake loading is generally ...

-Compaction is one of the efficient ways to improve the strength and stiffness properties of soils, such as elasticity modulus and shear modulus. Moreover, compaction decreases soil settlement, improves bearing capacity and the stability of sloped embankments. An optimum water content is required to provide the best path to enter energy into soil and compact it. A constant value of energy appli...

Determining the dynamic response of frozen soil is important for the study of the deformation, strength and stability of frozen soil under dynamic loading conditions for engineering design in cold regions. This paper discusses the recent progress in research on the dynamic response of frozen soil from the following three aspects: (1) influence of various testing conditions (confining pressure, ...

We make a comparison between the concepts and physics behind Youngs double slit experiment ⋀-δ ⋁-δ type three level atoms producing quantum interference.

1 2 Resilient modulus test is the recommended test to characterize subgrade soil for 3 pavement design in 1993 AASHTO pavement design guide as well as new proposed 4 Mechanistic-Empirical Pavement Design Guide (MEPDG). This test requires significant 5 resources including high level of technical capability to conduct. For smaller projects where 6 costly and complex resilient modulus testing is n...

Physical and mechanical properties of the drug-incorporated polymer play a significant role in release behavior from drug carriers. Understanding relative extent variation physical makes it possible to improve design carriers obtain better profile increase stability. Drug delivery PLGA loaded with various percentages diclofenac sodium (DS: 0, 5%, 10%) at different flow rates 0 7.5 ml/s (flow ra...

Offshore wind turbine (OWT) foundations are subjected to a combination of cyclic and dynamic loading arising from wind, wave, rotor and blade shadowing. Under cyclic loading, most soils change their characteristics including stiffness, which may cause the system natural frequency to approach the loading frequency and lead to unplanned resonance and system damage or even collapse. To investigate...

Seismic waves are filtered as they pass through soil layers, from bedrock to surface. Frequencies and amplitudes of the response wave are affected due to this filtration effect and this will result in different ground motion characteristics. Therefore, it is important to consider the impact of the soil properties on the evaluation of earthquake ground motions for the design of structures. Soil ...
