Nowadays bimrocks are widely used as a backfill material for artificial slopes and embank-ments, making the assessment of their shear strength properties a fundamental step for eval-uating the stability of such structures. Improved 2-D and 3-D limit equilibrium methods, re-vised with respect to previous studies to account for the difference in the peak pushing hori-zontal forces during the two loading cycles of the test, were applied to revise the assessment of shear strength parameters of some bimtests carried out in 2011.

It is a common construction practice to use mixtures of soils and rock fragments for engineered fills in slopes and embankments, making the assessment of their shear strength properties a fundamental step for determining the stability of such structures. In situ bimtests were performed in an artificial soil-rock mixture (S-RM) slope constructed for an electronic converter station in the Funing County, Yunnan Province, China.
