| چکیده | ||
| در این پژوهش نتایج مطالعات میدانی کاوش های ژئوالکتریکی زیرزمینی در مقیاس وسیع ارائه می شود. محدوده مورد مطالعه مسیر 14 کیلومتری اجرای خط نخست پروژه قطار شهری کرمانشاه است. مطالعه مقاومت الکتریکی خاک ها در عمق گمانه ها می تواند اطلاعات مفیدی در خصوص میزان استعداد خورندگی آنها در اختیار طراحان ابنیه بتن مسلح و فولادی قرار دهد. روش چهار الکترودی وِنِر مبنای اندازه گیری های صحرایی این مطالعه و ارائه یافته های آن است. جهت انجام آزمایش های مقاومت ویژه الکتریکی در اعماق مختلف گمانه های مسیر قطار شهری، از یافته های دقیق دستگاه Megger DET5/4D استفاده شده است. آزمایش های مقاومت الکتریکی در تعداد 15 گمانه در 12 ایستگاه مختلف پروژه در حداقل سه ژرفای 3، 5 و 7 متری انجام شده است. با توجه به مقایسه نتایج حاصله از این آزمایش ها و جدول رواداری ها، مقدار خورندگی خاک بر اساس معیار کمی خورندگی خاک رومانوف، در ایستگاه های 4، 6 و 9 در زمان انجام آزمایش ها، در حد متوسط تا شدید و در مابقی ایستگاه ها در حد متوسط است. نتایج میدانی این مطالعه در کنار یافته های مطالعات پژوهشی دیگر نشان می دهد که وجود رودخانه های قره سو و آبشوران درون شهر کرمانشاه و نشت فاضلاب به داخل این رودخانه ها و نیز وجود بسترهای خاکی رسی و آهکی گسترده، عامل اصلی شناسایی پتانسیل خورندگی متوسط تا شدید در اغلب نقاط شهر، به ویژه در نواحی مجاور این رودخانه ها هستند. | ||

| چکیده [English] | ||
| This research presents the results of field studies of large-scale underground geoelectrical explorations. The study area is the 14-km route of the first line of the Kermanshah urban train project. Studying the electrical resistivity of soils at the depth of boreholes can provide useful information about their corrosion susceptibility to designers of reinforced concrete and steel structures. The four-electrode Wenner method is the basis for the field measurements of this study and the presentation of its findings. To conduct electrical resistivity tests at different depths of urban train track boreholes, the precise findings of the Megger DET5/4D device were used. Electrical resistance tests have been conducted in 15 boreholes at 12 different stations of the project for at least three depths of 3, 5, and 7 meters. According to the comparison of the results of these tests and the tolerance table, the soil corrosion level, based on the Romanoff quantitative soil corrosion criterion, was moderate to severe at stations 4, 6, and 9 at the time of the tests, and moderate at the remaining stations. The field results of this study, along with the findings of other research studies, show that the presence of the Qarehsu and Abshuran rivers within Kermanshah city and the leakage of wastewater into these rivers, as well as the presence of extensive clay and calcareous soil beds, are the main factors in identifying moderate to severe corrosion potential in most parts of the city, especially in areas adjacent to these rivers. | ||
