Analysis of Reinforced and Un - reinforced Soil Slopes using Abaqus
Assessing the strength of soil slopes and investigating the means for increasing their safety against failure are crucial in construction projects involving large soil masses. Slope stability analyses have traditionally been performed using a limit state approach. However, any presence of reinforcement or local heterogeneity necessitates the use of numerical techniques such as finite element an...
متن کاملA Numerical Analysis on the Performance of Counterweight Balance on the Stability of Undercut Slopes
One of the important parameters in undercut slopes design is the determination of the maximum stable undercut span. The maximum stable undercut span is a function of slope geometry, the strength parameters of the slope material, condition of discontinuities, underground water condition, etc. However, the desired production capacity and therefore the size of excavating equipment will sometimes a...
متن کاملEffect of large blocks position on stability analysis of block-in-matrix slopes
Bimrocks are complex geomaterials that are defined as mixtures of rocks composed of geotechnically significant blocks within a matrix of finer texture. Bimslopes are made from bimrocks and are usually seen in weathered and shallow environments. Some characteristics of blocks affecting the strength of bimrocks include VBP (Volumetric Block Proportion), orientation, and arrangement, which have im...
متن کاملRoots and the stability of forested slopes
Root decay after timber cutting can lead to slope failure. In situ measurements of soil with tree roots showed that soil strength increased linearly as root biomass increased. Forests clear-felled 3 years earlier contained about one-third of the root biomass of oldgrowth forests. Nearly all of the roots < 2 mm in diameter were gone from 7-year-old logged areas while about 30 percent of the < 17...
متن کاملStability Analysis for Pitched Portal Frames of Fibre Reinforced Polymer
In this paper the analysis method from Majid (1963) for steel pitched portal frames is progressed so that we can study the influence of shearing action on the overall elastic critical buckling load when members are of Fibre Reinforced Polymer (FRP) material. For solid members of FRP the ratio of the longitudinal Young’s modulus to the shear modulus of elasticity can be significantly higher than...
