Uncertainty in fundamental natural frequency estimation for alluvial deposits
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 ...
متن کاملStochastic Analysis of Seepage through Natural Alluvial Deposits Considering Mechanical Anisotropy
The soil is a heterogeneous and anisotropic medium. Hydraulic conductivity, an intrinsic property of natural alluvial deposits varies both deterministically and randomly in space and has different values in various directions. In the present study, the permeability of natural deposits and its influence on the seepage flow through a natural alluvial deposit is studied. The 2D Finite Difference c...
متن کاملTypes of Martian Fan - Shaped Sedimentary Deposits
Introduction: Deltas, fans and channels on Mars clearly indicate surface water in the past. These landforms contain valuable information about the duration and magnitude of surface-water flow, with obvious implications for potential life on Mars. Martian fan-shaped deposits such as deltas and alluvial fans show architectural elements similar to those of terrestrial analogs, e.g. lobes, terraces...
متن کاملThe Importance of Soil and Alluvial and Quaternary Deposits Conditions in Seismic Risk Analysis
The land of Iran is a seismic active prone that is located in the mountainous and instable crust due to special geological position. Continuous tectonic stress from the Arabic and Indian plates has exposed seismic active faults. The huge and destructive earthquakes that occur every few years in this area reflect the tectonic conditions of the plateau of Iran. Since, the path of faults and fract...
