Offshore wind energy development is driven by ongoing research and to determine technological issues connected with offshore turbines. A fundamental design difficulty the turbine foundations. By far, one of most commonly practiced foundation systems mono helical pile foundations because their simplicity resilience. Most studies on piles were focused granular soils few clayey soils. However, in ...

Uplift modeling is a machine learning technique that aims to model treatment effects heterogeneity. It has been used in business and health sectors to predict the effect of a specific action on a given individual. Despite its advantages, uplift models show high sensitivity to noise and disturbance, which leads to unreliable results. In this paper we show different approaches to address the prob...

Original scientific paper In this paper, based on the overlapping deformation mode of load transfer law of uplift belled pile, and the theory of elastic mechanics, the elastic-plastic analytical solutions of uplift belled pile were derived, and the nonlinear elastic-plastic deformation analysis method was established, which made the deformation analysis theory of uplift belled pile more reasona...

Aboveground liquid storage tanks are often found on weak compressive soil due to their proximity harbours and rivers. These conditions lead a high probability of significant soil-structure interaction (SSI) under earthquake loading. In strong earthquakes, the transient partial separation tank base from supporting medium (uplift) chaotic sloshing cause damage wall. This experimental research det...

The Davisian model elucidates landscape development through an orogeny by denudation processes, postulating prolonged still-stand of a landmass following rapid tectonic uplift, ultimately resulting in a peneplain. The Penckian model emphasizes that landscape is shaped by concurrent tectonics and denudation, and includes the primary peneplain as an antithesis against the Davisian end-peneplain b...

We introduce Global Positioning System (GPS) Imaging, a new technique for robust estimation of the vertical velocity field of the Earth's surface, and apply it to the Sierra Nevada Mountain range in the western United States. Starting with vertical position time series from Global Positioning System (GPS) stations, we first estimate vertical velocities using the MIDAS robust trend estimator, wh...

• Cyclic tests of rocking columns restrained with a tendon-spring system are presented. The spring was designed so that the exhibits negative post uplift stiffness. One column's ends were protected by steel jackets while other one discs. two tested to 15% and 30% drift exhibited no damage. column reduces design moments on foundation. Letting sustain motion has been suggested as seismic method f...

Abstract Marine terraces have long been used as baseline geodetic markers of relative past sea levels, reflecting the interaction between vertical crustal movements and sea level oscillations. The terraces age and elevation of shoreline angles can be used to determine uplift rate. Disparate uplift rates in pervious investigation in the study area are related to manual measurements based on ...

[1] River incision over geologic timescales can be a valuable indicator of regional surface uplift. However, extracting the timing of surface uplift relative to the onset of incision is complicated by changes in precipitation commensurate with topographic development. Evidence of large-scale river incision on the flanks of the Andean plateau has been cited in support of a rapid and recent surfa...
