(ممکن است هنگام انتقال از فایل اصلی به داخل سایت بعضی متون به هم بریزد یا بعضی نمادها و اشکال درج نشود ولی در فایل دانلودی همه چیز مرتب و کامل است)

چكيده:

پایه های پل احداثی در کانال های روباز منجر به تغییرات حائز اهمیتی در الگوی جریان می گردند. هنگامی که جریان یک جهتی در یک کانال با یک مانع عمودی مواجه می گردد، به جریان سه بعدی تبدیل می شود، الگوی جریان حاصله در اطراف پایه پل پیچیده می شود. آبشستگی موضعی اطراف یک پای پل (استوانه ای) مسأله است که بیشتر مهندسان هیدرولیک با آن در گیرند. این یک مساله پیچیده است که از اندر کنش جریان آشفته سه بعدی اطراف استوانه و بستر متحرک کانال ایجاد می گردد. آبشستگی موضعی اطراف پایه های پل کی از متداول ترین علل شکست پل ها می باشد که بطور جدی نتایج زیانبار و غم انگیزی را موجب می گردد. آبشستگی موضعی پایه پل، یک موضوع مطالعاتی عمومی برای بیشتر مهندسان هیدرولیک گردیده است. 

 

مقدمه:

پل ها از جمله مهمترین و پرکاربردترین سازه های رودخانه ای بوده و به عنوان کلید راه های ارتباطی از اهمیت زیادی برخوردار هستند. هر ساله با وقوع سیلاب در هر رودخانه تعداد زیادی از این پل ها، درست زمانیکه بیشترین نیاز به آن ها وجود دارد تخریب می گردند. یکی از مهمترین و موثرترین عوامل این تخریب ها ابشستگی اطراف پایه های پل می باشد.
