The Response Analysis Of Granular Materials

Granular material structure is widely used in geotechnical engineering,there are more and more problems which related to structural dynamics of granular materials. However, in practical engineering is usually a continuous dielectric material or the classic rock and soil mechanics as a guide, Using the traditional design method of valuation.Many uncertainties are considered to remain unchanged, making construction there are many problems in the design tend to be conservative. Many parameters in the discrete material structure is variable and random, while many assume that is also uncertain.Based on AHP and stochastic process theory in combination with related engineering software, structural analysis of discrete material change in the uniform load and horizontal vibration loads response. Discrete material changes in the structure of uniform loads, the structure took place within the self-organization, due to the instability of self-organization, as well as the destruction of a single particle, the vertical load will fluctuate, there are fluctuations in the lateral displacement. Granular material in the level of vibration loads will occur in its internal granular particle separation will occur Brazil nut effect, anti-Brazil nut effect, sandwiches, and effects, etc., due to vibration effects, particles will occur between the re-composition and arrangement, resulting in discrete material different degrees of settlement structure.This study reveals the structure of granular materials under dynamic loading some of the mechanical properties of granular materials, the structure of theoretical research to do some additional hope that the findings derived from the actual works on a certain reference value.
