| چکیده | ||
| در پژوهش حاضر، رفتار سیکلی سیلت ماسهدار با رفتار سیکلی سیلت ماسهدار سیمانته محتوی سیمان و نانورس مقایسه شده است. خاک مورد استفاده در این پژوهش، ماسه 161 و لای غیرپلاستیک فیروزکوه با ترکیب 40 درصد ماسه و 60 درصد لای میباشد. در اینجا، اثرات فشار همهجانبه، کرنش برشی و جایگزینی نانورس بهجای سیمان بر پارامترهای مدول برشی و میرایی ماسه لایدار فیروزکوه تثبیت شده با سیمان و نانورس مطالعه شده است. به این منظور، آزمایشهای سهمحوری سیکلی با سه سطح فشار محصورکننده مختلف 50، 100 و 150 کیلوپاسکال در محدوده کرنش برشی متوسط انجام شد. نتایج مهم حاصل نشان داد که مقادیر مدول برشی نمونههای ماسه سیمانته با نسبت آب به سیمان 1، بیشتر از مدول برشی نمونههای ماسه سیلتی در تمامی محدودههای کرنش برشی مدنظر است. همچنین، مقدار مدول برشی با جایگزینی نانورس بهجای سیمان در نمونههای سیمانی شده افزایش یافت و بالعکس با افزودن سیمان، میرایی نمونهها کاهش یافت. با جایگزینی 20 درصد سیمان با نانورس مدول برشی بهطور متوسط 3 مگاپاسکال نسبت به نمونه سیمانته افزایش و میرایی بهطور متوسط 9/0 درصد نسبت به نمونه سیمانته کاهش یافت. با جایگزینی 40 درصد سیمان با نانورس نیز مدول برشی نسبت به نمونه سیمانته افزایش و میرایی کاهش یافت. برای بهبود پارامترهای دینامیکی خاک مورد آزمایش جایگزینی 20 درصد سیمان با نانورس کارایی بیشتری دارد. درحالت کلی، میتوان جایگزینی نانورس بهجای بخشی از سیمان را از منظر زیستمحیطی مورد توجه قرار داد. از سوی دیگر، با افزایش فشار محصورکننده، مقادیر مدول برشی تمامی خاکهای در نظر گرفته شده افزایش و میرایی آنها کاهش یافت. بهعلاوه، تأثیر مثبت افزایش فشار همهجانبه و افزودن نانورس برروی روانگرایی خاک مورد آزمایش نیز قابل مشاهده بود. | ||
