摘要:
在不同应力路径下,进行三轴和扭剪不排水剪切试验,揭示砂土力学行为与应力路径和各向异性的关系,并对砂土的细观结构和各向异性进行量化.研究结果表明,砂土的力学特性受材料各向异性和应力各向异性耦合影响.砂土各向异性的量化研究和力学试验结果为后续本构模型发展提供了依据.
Abstract:
The mechanical behavior of granular soil is very complex and strongly influenced by factors such as the density,confining pressure,drainage condition and loading path. An image analysis approach was used to quantify the fabric anisotropy of granular soil.Triaxial tests and torsional shear tests were done on Toyoura sand of different fabrics.The relations between the soil response and the fabric anisotropy were explored.The differences in the undrained stress-strain response among the differently prepared specimens are attributed to fabric anisotropy.
