Tóm tắt

Trước yêu cầu ngày càng cao về bảo vệ công trình trước các tác động nổ và xung kích, bê tông siêu tính năng (Ultra High Performance Concrete - UHPC) được xem là một vật liệu đầy triển vọng nhờ cường độ vượt trội và độ bền cao. Nghiên cứu này trình bày tổng quan về ứng xử của UHPC dưới tải trọng nổ, bao gồm cơ chế truyền sóng nổ, các dạng phá hoại đặc trưng và những yếu tố ảnh hưởng đến khả năng kháng nổ của UHPC. Các kết quả nghiên cứu thực nghiệm và mô phỏng số trên thế giới và trong nước được phân tích nhằm làm rõ ưu thế của UHPC so với bê tông thường trong điều kiện gia tải tốc độ cao. Bên cạnh đó, bài báo đánh giá thực trạng nghiên cứu trong nước, chỉ ra những hạn chế về cơ sở thực nghiệm, mô hình vật liệu, tiêu chuẩn thiết kế và năng lực sản xuất. Trên cơ sở đó, một số định hướng phát triển trong tương lai được đề xuất, bao gồm hoàn thiện mô hình vật liệu động, tối ưu hóa cấp phối ở cấp độ vi mô và ứng dụng các phương pháp mô phỏng số, học máy trong thiết kế kháng nổ. Kết quả tổng quan góp phần cung cấp cơ sở khoa học cho việc phát triển và ứng dụng UHPC trong các công trình yêu cầu mức độ an toàn cao trước tác động nổ tại Việt Nam.
