Granular mechanics approach to slope analysis
Web14 hours ago · The most important mechanical property of the resulting columns is the uniaxial compressive strength (UCS). The strength of a jet grouting improvement is expressed as a fraction of the UCS (usually between 0.2 and 0.3 times) considering the Tresca failure criterion ( Croce et al., 2014 ). On the other hand, there is a scientific … WebFeb 1, 2024 · In order to validate the combined SIMSAND-SPH approach, a series of DEM simulations is first conducted and used as benchmark data. More specifically, the 3D discrete element software PFC 3D coupled with the finite difference code FLAC 3D are used for the simulations.

WebOct 6, 2015 · Large landslides exhibit surprisingly long runout distances compared to a rigid body sliding from the same slope, and the mechanism of this phenomena has been studied for decades. Web3. Safety Factor Calculation and Analysis. The new approach was derived from cutting or foundation pit soil excavation. Slope engineering calculation examples in textbooks [26, 27] and literature were used to verify the general application of the calculation method with formula . Example 1.
Web8.1. Introduction. This section presents methods of analyzing stability of natural slopes and safety of embankments. Diagrams are included for stability analysis, and procedures for slope stabilization are discussed. Overstressing of a slope or reduction in shear strength of the soil may cause rapid or progressive displacements.
