Từ trước tới giờ, khi nghe nói về cọc chúng ta thường ít quan tâm tới trạng thái cọc chịu tải trọng nhổ. Với những công trình dạng Jacket trong CTB, việc chịu tải trọng ngang lớn, nền địa chất có nhiều san hô và đá cuội... thì việc cọc không đảm bảo khả năng chịu nhổ là kịch bản mà chúng ta phải tính tới. Dưới đây là một số hình ảnh về phương pháp sử lý cọc chịu tải trọng nhổ. Hình 1: Sử dụng hệ thống neo và vữa để neo cọc vào nền địa chất đá (Cọc thẳng) Hình 2: Sử dụng hệ thống neo và vữa để neo cọc vào nền địa chất đá (Cọc xiên) Hình 3: Sử dụng hệ thống mở rộng đáy cọc Hình 1: Sử dụng hệ thống neo toàn bộ cọc vào nền địa chất (đá, san hô)
