کنترل نشست در اعماق کم و محیطهای حساس یکی از مهمترین عملیات مهندسی تونل میباشد. دراین تحقیق پس از تحلیل عددی نشست تونل خط A مترو قم بوسیله نرم افزار FLAC که توسط TBM-EPB حفر شده بود و به دنبال آن معرفی روش حفاری مناسبی که با توجه به امکانات موجود در داخل کشور، علاوه بر میزان نشست کم این امکان را بدهد که هزینه و زمان ساخت یک سازه زیرزمینی با درجه قابل قبولی از دقت پیش بینی گردد، روش جدید حفار...
در عملیات احداث تونلها و فضاهای امن زیرزمینی همواره چالشها و مشکلات متعددی وجود دارد که اغلب روند پیشرفت کار را با کندی یا توقف مواجه میسازد. یکی از این چالشها حفاری در زمینهای سست بوده که در مناطق آبدار و در لایههای خاص، ساختاری ویژه را به وجود میآورد. لذا در چنین شرایطی آگاهی از روشهای مناسب جهت بهبود وضعیت زمین و روشهای حفاری مناسب به منظور دستیابی به حداکثر ایمنی و بازدهی عملیات بس...
It is widely known that a quick disclosure of the COVID-19 can help to reduce its spread dramatically. Transcriptase polymerase chain reaction could be more useful, rapid, and trustworthy technique for evaluation classification disease. Currently, computerized method classifying computed tomography (CT) images chests crucial speeding up detection while epidemic rapidly spreading. In this articl...
In recent years, structures made from monolithic reinforced concrete have been increasingly developed in the field of underground construction. This has possible by development modern tunneling technologies such as NATM and ADECO&RS, which proven themselves abroad. Being low-sedimentation methods construction, they found wide application not only mountain transport but also construction an ...
The 10.6 km long Sabzkuh water conveyance tunnel is currently under construction in High Zagros structural zone, located in western Iran, has used conventional (in section T1) and mechanized (in section T2) methods. The section T1 of the tunnel driven through alluvial geological units with great complexity in an area high potential for sliding and water-bearing fault which has made the excavati...
The study was designed to investigate the effects of dietary Selenium-enriched radish sprouts (Se-RS), Vitamin E (Vit E), and Rhodobacter capsulatus (RC) on immunity, cholesterol concentration, and fatty acid composition in broiler meat. A total of 100 two-week-old male broiler chicks were randomly assigned into five dietary groups: I) Control; II) Se-RS (5 μg/kg Se-RS); III) Se-RS+RC (5 μg/kg ...

Three common serial data standards, RS-232, RS-422, and RS-485, are described by specification and electrical interface. Cable termination techniques, use of multiple loads, daisy-chaining of RS-232, conversion of RS-232 to RS-485, conversion of RS-485 to RS-232, and RS-232 port-powered RS-485 conversions are described.
