Cấu trúc của địa đạo củ Chi lúc đầu rất đơn giản nhưng dần dần được cải tiến và đạt đến mức hoàn chỉnh, thuận tiện cho chiến đấu và sinh hoạt lâu dài trong lòng đất. Hệ thống địa đạo gồm một đường hầm chính và các đường hầm nhánh tỏa ra chằng chịt như mạng nhện trong lòng đất. Đặc biệt là địa đạo không thẳng tuột xuống mà nó ngoắt ngoéo và có nhiều tầng gọi tắt là tầng “trầm” (đi xuống) và tầng “thượng”  (đi lên). Đường hầm thường có kích  thước 50-60 cm bề ngang và 70-80 cm chiều cao, cũng có đoạn cao rộng  cho phép đi thẳng lưng và tránh nhau, hoặc có chỗ rất hẹp phải trườn mới qua được (gọi là điểm nút”, trần đường hầm hình vòm để có thể chịu được sức nén trên mặt đất. Từ đường hầm này sang đường khác hoặc lên “thượng” xuống “trầm” đều có nắp đậy và được ngụy trang khó phát hiện, muốn qua phải lách mình chui lên hay tuột xuống và thường được bố trí các hầm chông, hố đinh. Do địa hình, có những nơi, địa đạo có ba tầng như sau:

Tầng thứ nhất cách mặt đất từ 2,5 – 3,5m nối thong với nhiều ụ, ổ chiến đấu và giao thông hào. Chung quanh các ụ, ổ chiến đấu có bãi mìn, hầm chông…….

Tầng địa đạo thứ 2 cách mặt đất khoảng 5-6m dùng để nghỉ ngơi, sinh hoạt sau chiến đấu và trú ẩn của trẻ em, người già, phụ nữ, thương binh……..

Tầng thứ 3 cách mặt đất khoảng 8-10m, có nơi sâu đến 12m, có tác dụng tránh bom hạng nặng và xe ủi
