The tunnels located in the shallow depths of loose saturated sand are significantly prone to liquefaction-induced uplift. Research works are, therefore, progress propose efficient techniques for mitigating In this study, 1 g physical modeling was used assess performance helical piles decreasing effects pile length, number helixes, and spacing plan view were investigated. uplift mechanism tunnel...

We evaluate the applicability of generic Vickrey-Clarke-Groves (VCG) mechanism as an antimonopoly measure against a profit-maximizing producer with market power operating portfolio generating units at centralized two-settlement energy market. The may indicate in its bid not only altered cost function but also distorted values technical parameters units, which enter system-wide constraints dispa...

In their Comment, Zeitler et al. do not challenge our results or interpretation. Our study does not disprove coupling between tectonic uplift and erosion but suggests that this coupling cannot be the sole explanation of rapid uplift in the Himalayan syntaxes.

it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...

abstract among activities that can be used to prevent piping phenomena and reduce seepage and exit gradient are installation of cutoff wall and drain under hydraulic structures. hence in this study, to investigating the influence of each mentioned parameter on uplift force and exit gradient a computer model has developed in which general equation of fluid flow into the isotropic and anisotropic...

The surface uplift of mountain belts is generally assumed to reflect progressive shortening and crustal thickening, leading to their gradual rise. Recent studies of the Andes indicate that their elevation remained relatively stable for long periods (tens of millions of years), separated by rapid (1 to 4 million years) changes of 1.5 kilometers or more. Periodic punctuated surface uplift of moun...

12 The impact of the Tibetan Plateau uplift on the Asian monsoons and inland arid climates is an 13 important but also controversial question in studies of paleoenvironmental change during the 14 Cenozoic. In order to achieve a good understanding of the background for the formation of the 15 Asian monsoons and arid environments, it is necessary to know the characteristics of the 16 distribution...

To study the formation mechanism of lower shaft resistance uplift piles compared to compression piles, additional stress caused by and compressive in soil is obtained through indoor model tests with embedded micro earth pressure cells. The shows that pile has an unloading effect side soil, a loading soil. Closer point, becomes more obvious. decreases pile, increases pile. also reveal distributi...

I n their Comment on our study (1), Zeitler et al. (2) imply that we interpreted our findings to question the possible existence of feedbacks between surface and tectonic processes, which is not the case. We therefore appreciate the opportunity to clarify potentialmisunderstandings. Zeitler et al. (2) suggest that the oldest sediments at the base of the valley fill could be 3 to 4 million years...

Hotspot oceanic islands typically experience subsidence due to several processes related to migration of the oceanic plate away from the mantle plume and surface flexural loading. However, many other processes can interrupt subsidence, some of which may be associated with catastrophic events. A study of the biostratigraphy and sedimentology of Holocene deposits on Robinson Crusoe Island (RCI) o...
