Factors subjecting variability of Young’s modulus of cohesive soils
Języki publikacji
Abstrakty
The paper presents analysis of factors that subject a value o f Young's m odulus of cohesive soils. This parameter is indispensable in a design process of all soil structures and any engineering structure founded on soil. According to Polish practice expressed in Polish Standard PN-81/B-03020, value of Young’s modulus is uniquely related to soil kind and liquidity index. The paper presents considerably larger number of factors that influences deformation of soils with particular reference to strain range, State of stress and its history. From this results that Young's modulus should be perceived rather as deformation characteristic dependent on many factors and not material constant. The theses presented in the paper are exemplified by experimental data.
