Abstract AR
يعرض هذا البحث نتائج دراسة معملية للجرف الموضعي عند نماذج للحوائط المساندة للجسور.
عملت هذه النماذج على ثلاثة أشكال متعارف عليها، و وضعت في قناة معملية فرشت أرضيتها برمل منتظم الحبيبات (d50 = 0.775 mm).
تم إيجاد أعلى قيمة لأعماق الجرف، و مدى امتدادها تحت ظروف المياه الرائقة، و اقترحت معادلة عامة لابعدية لتقدير الجوف في المياه الرائقة.
تأخذ المعادلة كل المتغيرات الهامة بدلالة شكل و مقاس الحائط الساند، و خصائص الرواسب و الجريان، و تم التحقق من المعادلة باستخدام البيانات المعملية الحالية بالإضافة إلى بيانات أوجدها باحثون سابقون تحت ظروف مشابهة.
Abstract EN
This paper presents the results of an experimental investigation of local scour at bridge abutment models of three common shapes placed in labo- ratory Hume with uniform sand with < / 5ll = 0.775 mm.
The maximum scour depths and extent of scour were determined corresponding to clear water con- ditions.
For design purposes, a general nondimensional equation for clear water scour prediction is proposed.
The equation addresses all the important variables in terms of shape and size of abutment, sediment and flow character- isties.
The equation was verified with the present experimental data as well as with the data obtained by previous investigators under comparable conditions.
