Gravity anchor blocks are a common type of ground used for suspension bridges, whose bearing depends on its large body and gravity. As there is no stratum requirement, the safety block important bridge stability. This study summarizes all available estimation indexes, calculating methods, evaluation criteria gravity Ruili bank Banjin Dam grand bridge. The anti-overturning, anti-sliding, base st...

Using the “CLIMBER-3 ” coupled climate model of intermediate complexity, the effect of a stratification-dependent vertical diffusivity on the sensitivity of the Atlantic Ocean meridional overturning circulation to perturbations in freshwater forcing is investigated. The vertical diffusivity is calculated as N , where N is the local buoyancy frequency and the parameter is a measure of the sensit...

A meridional-plane, hemispherical ocean model is developed to study interdecadal variability of the thermohaline circulation (THC). The model differs from previous formulations of zonally averaged ocean models by using a prognostic equation to calculate the meridional velocity. This allows the incorporation of an adjustment timescale comparable to the advective timescale of the meridional overt...

Three-dimensional (3D) directional wave focusing is one of the mechanisms that contributes to the generation of extreme waves, also known as rogue waves, in the ocean. To simulate and analyze this phenomenon, we generate extreme waves in a 3D numerical wave tank (NWT), by specifying the motion of a snake wavemaker. The NWT solves fully nonlinear potential flow equations with a free surface, usi...

A pre-design guide for cantilever retaining walls and a detail parametric study of such is presented here. Mathematical models based on statistical methods were improved calculating safety factors sliding, overturning, slope stability those walls. The harmony search algorithm (HSA)-a metaheuristic optimization method-was employed to realize reasonable results the from all distinct cases. Throug...

Changes in the Atlantic overturning circulation have a strong influence on European temperatures, North American sea level and other climate phenomena worldwide. A meaningful assessment of associated societal impacts needs to be based on the full range of its possible future evolution. This requires capturing both the uncertainty in future warming pathways and the inherently long-term response ...

[1] From the interpretation of different proxy data it is widely believed that the North Atlantic thermohaline circulation during the maximum of the last ice age !21,000 years ago was considerably weaker than today. Recent equilibrium simulations with a coupled ocean-atmosphere-sea ice model successfully simulated a reduction in North Atlantic Deep Water (NADW) formation consistent with reconst...
