| چکیده | ||
| از گروه شمع بهعنوان پی ساختمانها، پلها و برجهای انتقال استفاده میگردد. در محیطهای شهری بهدلیل عدم امکان استفاده از شمع کوبشی (Driven Pile) معمولاً از شمعهای حفاریشده که دارای ظرفیت باربری کمتری نسبت به شمع کوبشی هستند، استفاده میگردد. یکی از روشهای متداول افزایش ظرفیت باربری شمعهای حفاریشده، استفاده از روش تزریق پرفشار دوغاب سیمان در نوک شمع میباشد. درخصوص رفتار گروههای شمع پستزریق شده (Post Grouted Drilled Pile) در مجاورت شیروانی تاکنون تحقیقی صورت نگرفته است. در این تحقیق، بهکمک روش المان محدود و با استفاده از نرمافزار PLAXIS3D به بررسی اثر شیروانی ماسه ای برروی ظرفیت باربری، ضریب راندمان و میزان چرخش سرشمع گروههای شمع پستزریق شده پرداخته میشود. در این تحقیق، گروههای شمع پستزریق شده 2×2، 1×2 و 1×3 با قطر 1، 5/1 و 2 متر، با نسبت طول مدفون به ارتفاع شیروانی 33/0، 67/01 و فواصل شمع 3، 4 و 5 برابر قطر شمع، در مجاورت شیروانی ماسهای به ارتفاع 30 متر و شیب 30 درجه بهصورت سهبعدی مدل گردیدند. اثر عوامل مختلفی همانند قطر شمع، نسبت طول مدفون به ارتفاع شیروانی و فاصله شمعها از یکدیگر برروی ظرفیت باربری گروه شمع پستزریقشده در نوک شمع مورد بررسی قرار گرفت. نتایج نشان داد، پروسه پستزریق باعث کاهش چرخش سرشمع گردید. با افزایش فاصله شمعها از یکدیگر و افزایش قطر شمعها، ضریب BCR افزایش یافت. اثر پروسه پستزریق برروی افزایش ظرفیت باربری و کاهش چرخش سرشمع گروه شمع خطی (Linear Pile Group) موازی رأس شیروانی، بیشتر از گروه شمع خطی عمود بر رأس شیروانی بود. | ||
