چکیده

امروزه یکی از مشکلات اساسی در پروژه ­های عمرانی و ژئوتکنیک، مرتبط با خاک در محل پروژه می ­باشد که در آن خاک به ­عنوان یک مصالح طبیعی، مقاومت کافی برای تحمل بارهای وارده را نداشته باشد. خاک طبیعی موجود در محل پروژه ­ها در بعضی مناطق حتی اگر مناسب برای ساخت­ وساز نیست، با استفاده از روش­ های نوین می­توان خصوصیات ژئوتکنیکی و فیزیکی آن ارتقا داد. در این مقاله، اثر الیاف بازالت و نانوسیلیس به ­عنوان یک مصالح جدید بر روی مقاومت فشاری و پارمترهای مقاومت برشی نمونه ­های ماسه ­ای لای­ دار با استفاده از آزمایش تک ­محوری و سه­ محوری مورد بررسی قرار گرفته است. نتایج آزمایش­ های تک ­محوری نشان می­دهد که اضافه شدن الیاف یا نانوسیلیس هر دو باعث افزایش مقاومت فشاری نمونه ­ها شده است، اگرچه اثر نانوسیلیس در افزایش مقاومت تک محوری با گذشت زمان بیشتر از اثر الیاف است. ترکیب الیاف بازالت و نانوسیلیس می­توان اثر مهم­تری بر روی افزایش مقاومت تک محوری نمونه ­ها داشته باشد. نتایج آزمایش ­های سه­ محوری استاتیکی افزایش پارامترهای مقاومت برشی نمونه ­ها را به ­ازای اضافه شدن الیاف و نانوسیلیس نشان می­دهد. همچنین اعمال سیکل ­های ذوب و یخبندان تا حدودی باعث کاهش پارامترهای مقاومت فشاری شده است.

چکیده [English]

Weak soils with unfavorable geotechnical characteristics cause many technical and economic problems in construction projects such as road construction. One of the solutions to the problem is soil improvement (Asgari et al., 2015; Bayat et al., 2021; Eshaghzadeh et al., 2021; Hadi Sahlabadi et al., 2021; Hakimelahi et al., 2023; Rezaei-Hosseinabadi et al., 2022, 2022; Saadat and Bayat, 2022; Tavakol et al., 2023). Many materials such as fiber, cement, lime, nanomaterials etc. have been used to improve of soils. On the other hand, previous studies indicate that freeze-thaw cycles have an important effect on the mechanical behavior of geomaterials (Hadi Sahlabadi et al., 2021; Noroozi et al., 2022; Roustaei, 2021).
