For example, maximum excess pore pressure at failure state and corresponding deviatoric stress are respectively useful in analysis of generated excess pore pressure and adopting cyclic stress ratio in cyclic strength tests over gravelly materials. Maximum monotonic strength is used in selection of induced anisotropy ratios before dynamic testing. Moreover, for saturation collapse test of rockfill material, selection of the level of shear stress in dry-saturated is required dry monotonic tests. During 1994 to 2017, 150 large monotonic triaxial tests are carried out on high compacted rockfill materials and engineering filling under drained and untrained conditions. Mechanical behavior of engineering filling and rockfill materials is depended on mineral composition, grain size distribution, drainage conditions, ranges of confining pressures, particle breakage index, size and shape of grain. Due to similarity of materials behavior with same characteristics, especially about the effect of particle size distribution and confining pressure, assessment of previously obtained results is very useful.  UR - https://behs.bhrc.ac.ir/article_154893.html L1 - https://behs.bhrc.ac.ir/article_154893_2ef9734c928125c3f26f2e936e9a896f.pdf ER -
