[ 1 ] - اثر موقعیت پایه پل استوانهای بر عمق آبشستگی در قوس 180 درجه رودخانهها
In this research, the effect of installing position of bridge pier on scouring depth was studied in a bend laboratory flume, which is made of Plexiglas with 180 bend and a relative radius of Rc/B=4.7. Tests were conducted using one pier 6 cm in diameter under four discharge conditions with constant depth of 12 cm and clear-water conditions. Flume bed was fully paved by uniform sand. It was foun...
[ 2 ] - بررسی آزمایشگاهی اثر طوقه در کنترل آبشستگی اطراف پایه پل استوانهای در قوس 180 درجه رودخانه
Every year river flooding causes serious damage to the bridges at the time needed most. One of the most effective factors causing bridge failure is scouring around the piers in a river bend. One of the methods to decrease scouring around the bridge piers is fitting them with a coller on the piers. The collars protect the river bed against vortex flow in the vicinity of the pier base. An experim...
