Experimental Investigation of Submerged Vanes’ Shape effect on river-bend stability
In river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend. A helical motion results, causing erosion of the outer side of the bend. Installation of submerged vanes on the stream bed can reduce erosion of the outer bank significantly. In th...

15 صفحه اولStudy of Loose Soil Layer Effects on Excavations Supported by Steel Sheet Pile Walls – A Numerical Study
Abstract Steel sheet pile walls are being widely used in civil engineering projects for support systems. Soil is not uniform in depth, sometimes may be exit loose or soft soil layer in various depth. This issue can cause different effects on ground surface displacements, forces and moments acting on sheet piles and struts during excavation procedure, compared with status that soil is uniform...
متن کاملتأثیر توأم صفحات مستغرق و طوق در کاهش عمق آبشستگی پایه‌های استوانه‌ای شکل پل‌ها
Submerged vanes are low aspect ratio flow-training structures mounted vertically on the river bed at an angle to the prevailing flow. The aim of application of vane is to generate a secondary circulation in the main flow, designed to modify the near-bed flow pattern and thus redistribute flow and sediment transport within the channel cross section. Collar is a flat sheet with low thickness fixe...
