Tối ưu hóa tham số và phân tích hồi quy đa biến cho kỹ thuật đóng cọc đất sử dụng các phương pháp số
Tóm tắt
Kỹ thuật đóng cọc đất đã trở thành một phương pháp chính trong việc giữ đất và ổn định độ dốc. Nghiên cứu hiện tại thực hiện tối ưu hóa tham số tiềm năng trong kỹ thuật đóng cọc đất bằng cách xem xét tương tác giữa cọc và phân tích ngược sức kéo của cọc sử dụng Phân tích phần tử hữu hạn với PLAXIS 2D. Kết quả cho thấy sức kéo của cọc phụ thuộc vào độ sâu, từ đó cung cấp phương hướng tiềm năng cho việc tối ưu hóa mô hình chiều dài cọc đất. Xu hướng kết quả quan sát đã được xác nhận thêm bằng Phân tích Cân bằng Giới hạn. Hơn nữa, phân tích động đã được thực hiện để đảm bảo sự ổn định động đất xem xét mô hình chiều dài cọc giảm theo các hướng dẫn của FHWA và các phương pháp số như phương pháp phần tử hữu hạn và phương pháp cân bằng giới hạn. Các kết quả cho thấy rằng xu hướng quan sát với các mô hình chiều dài cọc giảm đã gây ra sự gia tăng nhẹ trong các điều kiện sử dụng như biến dạng ngang, nhưng các kết quả được quan sát vẫn nằm trong giới hạn cho phép trong trạng thái giới hạn cuối cùng. Ngoài phân tích số, một phân tích hồi quy số đã được thực hiện để phát triển mối tương quan giữa các tham số địa kỹ thuật, các mô hình chiều dài cọc và các điều kiện giới hạn.
