Static and Seismic Stability of Cut Slopes in Terms of Reliability
… for evaluating the static stability of a cut slope formed by strain-softening soil such as highly overconsolidated clay considering progressive failure as the critical failure mode. The stress condition along a potential failure surface both prior to and after an excavation is investigated …

Erosão superficial em taludes de corte em solo Residual de Gnaisse
Study of superficial erosion of cut slopes. It is divided into two parts. The first part consists of a laboratory investigation where, by means of test results, the relative erodibility of various layers of gneissic residual soils was compared. Also in this part, an attempt was made to correlate …

Impact of Freeze-Thaw Cycles on Porosity Change in Shalles and Its Implications on Erodibility
Cut slopes for transportation assets can expose near-surface shales, which are highly degradable materials. Initially, these cuts appear stable, but the material can quickly weather into loose sediment. Predicting this degradation is essential because intact shale is a stable, non-erodible …

Building, Updating and Verifying Fracture Models in Real Time for Hard Rock Tunneling
… limited amount of data from boreholes, outcrops, cut slopes, and geophysical surveys. In tunneling, the process of excavation creates a priceless opportunity to gather more data during construction. Typically, however, these data are not utilized due to the impedance of sampling and analysis on …

Meaning, measurement, and field application of fully softened shear strength of stiff clays and clay shales
… shear strength in the failure of natural and cut slopes is important for design and stability evaluation. The intact shear strength is rarely available at the time of first-time slope failures. It is generally accepted that only residual shear strength is available for the reactivated …

Use and Measurement of Fully Softened Shear Strength
… of the fully softened shear strength for slopes is based on back-analyses. Back-analyses of first-time failures in cuts in stiff-fissured clays and embankments constructed of fat clays have shown that, over a long period of time, the shear strength gets reduced from what is measured in the …
