چکیده
کاربرد گسترده ساختارهای صفحه‌ای در پروژه‌های عمرانی به دلیل سبکی، استحکام و صرفه‌جویی اقتصادی، اهمیت استفاده از آنها را دو چندان می‌کند. در این پژوهش برای کاهش سیر صعودی ضخامت دیوارهای حائل وزنی بتنی و به تبع آن کاهش سیر صعودی مصالح مصرفی به ازای افزایش ارتفاع دیوار، دال های مسطح با دیوارهای حائل وزنی بتنی تطبیق گردیده و یک نوع دیوار حائل سبک سازی شده جدید پیشنهاد گردیده است، سپس تلاش شده تا بنیان نظریه صفحات و جنبه های فیزیکی و ریاضی مباحث و کاربرد آن در مطالعات انجام شده برای دیوار حائل جدید مهیا شده و معادلات حاکم برای حالت مسئله پیشنهاد شده، ارائه شود. نتایج نشان می هد که دیوار حائل جدید، از نظر مصرف بتن به طور قابل توجهی مقرون به صرفه خواهد بود. بطور کلی در این پژوهش روش جدیدی بر پایه اصول ریاضی برای محاسبه و آنالیز دیوار حائل سبک سازی شده مرکب از دال های تخت ارائه گردیده است.

چکیده English

The widespread use of plate structures in construction projects due to their lightness, strength and economic efficiency doubles the importance of using them. In this study, in order to reduce the upward trend of the thickness of concrete gravity retaining walls and consequently reduce the upward trend of the materials consumed for increasing the height of the wall, flat slabs are adapted to concrete gravity retaining walls and a new type of lightweight retaining wall is proposed. Then, an attempt has made to provide the basis of plate theory and the physical and mathematical aspects of the topics and its application in the studies conducted for the new retaining wall, and the governing equations for the proposed problem state is present. The results show that the new retaining wall will be significantly more economical in terms of concrete consumption. In general, in this study, a new method based on mathematical principles presented for calculating and analyzing a lightweight retaining wall composed of flat slabs.
