Retaining cantilever walls are typically designed under drained conditions, assuming that proper drainage is implemented, correctly constructed, and functions throughout the structure's lifespan. However, when appropriate drainage cannot be constructed—such as in walls that cut into and retain a natural slope, where the wall is built adjacent to nearly vertical excavated soil, designers...
The rock slope stability in seismically active regions is a critical aspect for safe and sustainable quarrying. This study investigates the effect of seismic loading on the stability of a dolomite quarry, integrating traditional analytical methods with advanced two-dimensional finite element models. The site, located near a historically active earthquake zone, provides an ideal environment to...
Major earthquakes cause displacements primarily due to seismic accelerations, which affect the frictional strength of underlying soils. It is anticipated that the total displacement of sloped soils in earthfill dams triggered by an earthquake is influenced by the magnitude and frequency of the seismic event. This underscores the importance of numerical simulations that incorporate a broader...
Soils' local geological and geotechnical properties may lead to sharp variations of seismic shaking and structural damage at small distances. These so-called seismic site effects significantly impact the amplitude and frequency components of the ground motion. Key site effect parameters are the shear wave velocity of soils (Vs), indicating the material stiffness, and the fundamental vibration...
A vast majority of experimental results have been accumulated to assess the shear modulus of various soils at very small levels of strains., so called small strain modulus or maximum shear modulus, Gmax. The cyclic triaxial test procedure due to overriding popularity in recent decades has become widely used methods for measuring modulus and damping. For fine granular soil materials Cyclic...
The landslide is the movement of soil and rocks down a slope, as a result of the loss of shear strength in the material that builds the slope. Although various human activities increase the risk of landslides, the most common causes for the loss of shear strength are geological and morphological. Thus, natural triggers for landslides can be the characteristics of the soil and rocks that build...
The assessment of liquefaction potential is critical in regions subject to seismic activity, as it can cause significant damage to buildings and infrastructure. However, the reliability of liquefaction potential evaluations is highly dependent on the assessment methods employed and the number of representative investigations conducted. This issue is particularly pertinent when assessing linear...
Contemporary living and the need for renewable energy sources demand innovative “green” technologies that offer structural improvement and simultaneously provide more economical and long-term cost-friendly solutions. In geotechnical engineering, shallow thermo-active geo-structures look like one of the most promising concepts. Thermo-active geo-structures may include base slabs, piles,...
