Friction Structure Effect Analysis of Granular Materials in Foundation Soil
To research and analyze the additional stress distribution and change of granular materials,the model tests are used to observe vertical additional stress in different position and depth.And the comparison between observed values and theoretical values is conducted to analyze the transmission and attenuation of additional stress in granular materials.The research results show that calculated values are based on Boussinesq solution which ignores the property of soil layer (materials),the distribution of additional stress for fine sand which belongs to granular materials is largely deviated from theoretical value.For granular materials,inner friction structure effect is evident influence to additional stress transfer.And continue using calculation method which is based on continuum materials will have bigger difference and even wrong.
