| پژوهش حاضر با هدف پهنهبندی ژئوتکنیکی خاک شهر اهواز با استفاده از سیستم اطلاعات جغرافیایی (GIS) انجام شد. با جمع آوری اطلاعات ژئوتکنیکی حاصل از 330 گمانه حفاری شده تا عمق 20 متری و با بکارگیری نرمافزار سیستم اطلاعات جغرافیایی (ArcGIS) پارامترهای ژئوتکنیک خاک در شهر اهواز پهنهبندی گردید. عوامل تاثیرگذار بر ظرفیت باربری خاک شامل چسبندگی خاک، زاویه اصطکاک داخلی و وزن مخصوص خاک جهت پهنهبندی انتخاب شدند. نقشه درونیابی پهنهبندی شده زاویه اصطکاک داخلی در شهر اهواز نشان داد که با افزایش عمق خاک، زاویه اصطکاک داخلی افزایش داشته است. با افزایش عمق، زاویه اصطکاک داخلی افزایش داشته است، بطوری که در عمق 10 متر، در اغلب گمانههای حفر شده در مناطق مذکور، میزان زاویه اصطکاک داخلی به 41 درجه افزایش داشته است. بطوریکه در در محدوده شمالشرق اهواز بیشترین میزان زاویه اصطکاک داخلی وجود ثبت شد. نتایج حاصل از نقشه پهنهبندی چسبندگی بر اساس گمانههای حفر شده نشان داد که ارتباط آماری بین این مولفه ژئوتکنیکی و افزایش عمق وجود ندارد. همچنین بررسی وزن مخصوص خاک بر اساس گمانههای حفر شده و نقشه درونیابی پهنهبندی شده در تحقیق حاضر نشان داد که با افزایش عمق خاک، میانگین وزن مخصوص افزایش معنیداری داشته است و از 1/6 درصد در عمق 2 متر به 47/9 درصد در عمق 10 متری رسیده است. بطور کلی این مولفهها به ویژه وزن مخصوص، با تعیین ظرفیت باربری خاک مرتبط بوده میتوان از آنها برای امکانسنجی انتخاب بهترین گزینه مکانی جهت احداث پروژههای خاص بهرهگیری نمود. | ||

| The present study, which is of an applied type, was conducted in 1400 with the aim of geotechnical zoning of the soil of Ahvaz city using GIS. By collecting geotechnical information obtained from 200 drilled boreholes to a depth of 10 meters and using ArcGis software, soil geotechnical parameters were zoned in Ahvaz. Factors affecting soil bearing capacity including soil adhesion, internal friction angle and soil specific gravity were selected for zoning. The results of stress calculations showed the existence of a linear increase relationship between its values at different soil depths. The zoned interpolation map of internal friction angle in Ahvaz city showed that with increasing soil depth, internal friction angle has increased. The highest internal friction angle at a depth of 2 meters was recorded in the northeast of Ahvaz (Kianpars area) with more than more than 41 degrees. With increasing depth, the internal friction angle has increased, so that at a depth of 10 meters, in most boreholes drilled in the mentioned areas, the amount of internal friction angle has increased to more than 41 degrees. The results of the adhesion zoning map based on the drilled boreholes showed that there is no statistical relationship between this geotechnical component and the depth increase. Also, the study of soil specific gravity based on drilled boreholes and zoning interpolation map in the present study showed that with increasing soil depth, the average specific gravity increased significantly from 1.6% at 2 m depth to 47.9% at depth 10 Meters has been reached. In general, these components, especially specific gravity, are related to determining the load-bearing capacity of the soil and can be used to assess the feasibility of choosing the best spatial option for the construction of specific projects. | ||
