[ 1 ] - Laboratory Study on the Effect of Water Cations’ Concentrations on the Bojnord Clay Consolidation Process
The initial consolidation settlement process of saturated cohesive soils has been one of the most important issues to geotechnical engineers especially in important and sensitive structures based which are located on saturated clay layer with high thickness. In dealing with initial consolidation settlement process and reducing its negative and destructive consequences, a number of solutions ha...
[ 2 ] - Cracks Analysis in Zavin Concrete Dam Using Fracture Mechanics Approach
Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...
[ 3 ] - Experimental Study on the Effect of Crumb Rubber on Shear Strength of Sandy Soil
Nowadays, soil reinforcement using polymer elements have been investigated by a number of researchers in order to increase the load capacity of soils. Reinforcing soils using fibers is a method of soil improvement, which offers a homogenous mixture in combination with soils, regarding their tensile strength. This combination maintains pressure loading capacity and properties in mutual resistant...
[ 4 ] - Numerical Modeling of the Effect of Geocell Elements’ Dimensions on Behavior of Circular Footings
Use of auxiliary elements in refining and betterment of engineering properties of soil have gained attention since a long time ago. Nowadays the effectiveness and capability of the soil reinforcing technique for giving proper practical solutions in various projects have resulted in this technique quickly gaining a place in geotechnical engineering. In this paper, the results of laboratory studi...
[ 5 ] - Effect of the Cylindrical Reinforcing Element’s Filling Materials on the Soil’s Resistance
In this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from SM to GM on behavior of sandy soil. In this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 KPa were carried out in ...
[ 6 ] - An Investigation on the Behavior of Retaining Structure of Excavation Wall Using Obtained Result from Numerical Modeling and Monitoring Approach. (A Case Study of International "Narges Razavi 2 Hotel", Mashhad)
With the growing population and density in metropolitan areas, higher tendency to live in high-rise buildings, and increasing demand for parking lots, it seems necessary to excavate soil to construct underground spaces. During excavation work, as the height of the wall increases, special care should be taken to the wall stabilization to avoid any consequent damage including extensive property d...
[ 7 ] - تحلیل برگشتی رفتار سد خاکی تبارکآباد ایران با استفاده از نتایج رفتارسنجی و مدل‌سازی عددی
یکی از مهمترین مراحل بعد از مطالعات ژئوتکنیک، طراحی و احداث سد، بررسی رفتار سد در دوران بهرهبرداری میباشد که در این راستا رفتار سد در مراحل مختلف ساخت، آبگیری و دوران بهرهبرداری توسط ابزارهای دقیق نصب شده، قابل ارزیابی میباشد. سد خاکی تبارکآباد با ارتفاع حداکثر 50 متر از کف و 74 متر از بستر سنگی دارای هستهای رسی بوده و در 25 کیلومتری شمال شرقی شهر قوچان از استان خراسان رضوی بر روی رودخان...
[ 8 ] - اولویت بندی ترمیم و بازسازی پل های بتنی شبکه راه های استان خراسان رضوی با استفاده از روش تحلیل سلسله مراتبی
با توجه به ضرورت توسعه شبکه راههای کشور، پلها به عنوان سازه های زیربنایی، نقشی کلیدی در امداد رسانی و تداوم فعالیتهای حیاتی در مرحله بازیابی پس از بروز حوادث و بلایای طبیعی را بر عهده دارند. در استان خراسان رضوی با توجه به شرایط اقلیمی و آب و هوایی از یک سو و وجود نمکهای خورنده در پروفیل خاک بسیاری از مناطق و همچنین وجود رودخانه های فصلی با شوری آب بالا از سوی دیگر، بسیاری از ابنیه فنی راههای ا...
[ 9 ] - بررسی رفتار سد خاکی چهچهه با استفاده از نتایج رفتارسنجی و تحلیل برگشتی
بررسی رفتار سدهای خاکی در حین دوران ساخت، پایان ساخت و همچنین اولین دوره آبگیری به عنوان یکی از بحرانی‌ترین زمان‌ها در طول عمر سد، به دلیل تنش‌های ایجاد شده و فشار آب منفذی در هسته با توجه به وضعیت تراز آب در این دوره از اهمیت ویژه‌ای برخوردار است. به همین منظور در این تحقیق رفتار سد خاکی چهچهه با استفاده از نتایج رفتارسنجی و تحلیل برگشتی به کمک نرم‌افزار المان محدود GeoStudio مورد مطالعه قرار ...
[ 10 ] - A Study on the Effects of Waste Rubber Tire Dimensions on Fine-Grained Soil Behavior
Mashhad city is located on alluvial deposits where the expanded area of this city, especially the central and eastern areas surrounding Imam Reza holy shrine, are built on weak and fine-grained deposits. Therefore, the soil improvement would be inevitable due to construction of high-rise buildings such as hotels and commercial complexes in these areas, as well as restructuring old buildin...
