offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. a safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. while the cost...

Anchors are widely used in foundation systems for structures requiring uplift resistance. As demonstrated by numerous theoretical and experimental studies on the subject, uncertainty remains as to both the theoretical uplift capacity of anchors in idealised soils and the suitability of the various modelling assumptions in capturing the responses observed during tests. This study, which deals ex...

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 ...

We define uplift and denudation, then review the basic principles underlying the mechanisms for producing uplift, and the methodologies used to quantify the geological timescale denudation history of uplifted regions. Uplift is represents work done against gravity, and does not necessarily lead immediately to rapid denudation. The causes of uplift can be categorised according to the principal d...

This paper presents new theoretical predictions of the undrained uplift capacity of deeply embedded inclined strip anchors in a soil stratum with a linear variation of strength with depth. Rigorous bounds on the theoretical uplift capacity are presented using upper and lower bound limit analysis. The effects of the strength gradient on the normalised uplift capacity and the predicted failure me...

Long-standing debates exist over the timing and mechanism of uplift of the Tibetan Plateau and, more specifically, over the connection between lithospheric evolution and surface expressions of plateau uplift and volcanism. Here we show a T-shaped high wave speed structure in our new tomographic model beneath South-Central Tibet, interpreted as an upper-mantle remnant from earlier lithospheric f...

The topography of the eastern Southern Alps (ESA) reflects indenter tectonics causing crustal shortening, surface uplift, and erosional response. Fluvial drainages were perturbed by Pleistocene glaciations that locally excavated alpine valleys. The Late Miocene desiccation of the Mediterranean Sea and the uplift of the northern Molasse Basin led to significant base level changes in the far fiel...

To clarify the Holocene uplift history of the Izu Islands, Japan, we analyze the elevations and C ages of emerged sessile assemblages measured by accelerator mass spectrometry (AMS) on the islands of Niijima, Jinaijima, Shikinejima, and Kouzushima, on the northern Zenisu Ridge. The results suggest that uplift events took place after AD 1950 (uplift event 1), during AD 786–1891 (uplift event 2),...
