Abstract    In this paper, a mesh-free approach called smooth particle hydrodynamics (SPH) is proposed to analyze the seepage problem in porous media. In this method, computational domain is discredited by some nodes, and there is no need for background mesh; therefore, it is a truly meshless method. The method was applied to analyze seepage flow through a concrete dam foundation. Using the SPH method, the computational boundary being coincident with the physical boundary, was numerically acquired by solving seepage flow govern in equations. The numerical results of the presented method were compared with ones calculated by the Geostudio-SEEPW (finite element based software). The water head values were calculated through the dam foundation, and there was a good agreement between results. Moreover, results showed that the SPH method is efficient and capable of analyzing seepage flow particularly in complex geometry problems.

چکیده   

مقاله حاضر به بررسی روش بدون شبکه هیدرودینامیک ذرات هموار شده جهت آنالیز نشست آب در محیط های متخلل می پردازد. در این روش محدوده محاسباتی به وسیله تعدادی گره گسسته سازی شده و هیچ نیازی به شبکه بندی محیط حل در این روش نمی باشد. لذا این روش کاملا روشی بدون شبکه می باشد. از روش ارائه شده جهت شبیه سازی و انالیز نشت آب در فونداسیون سدهای بتنی استفاده شده است. با استفاده از روش (SPH)، محدوده محاسباتی که با محدوده فیزیکی منطبق بوده است، بصورت عددی با حل معادلات حاکم بر نشت آب حاصل شد. نتایج حاصل از روش ارائه شده با نتایج حاصل از مدل سازی توسط نرم افزار تحلیل نشت (Geostudio-SEEPW) مورد مقایسه قرار گرفت. مقادیر هد آب در تمامی طول فونداسیون سد محاسبه گردید و نتایج از همخوانی و دقت قابل قبولی برخوردار می باشند. با بررسی روش هیدرودینامیک ذرات هموار شده مشخص گردید که این روش از توانایی قابل توجهی در آنالیز نشت به ویژه در محیط هایی با هندسه های پیچیده برخوردار می باشد.
