[0002] Tunnel engineering plays a vital role in modern urban construction and underground space development. With the accelerated development of urbanization, the demand for efficient and safe tunnel construction technology is growing. Tunnel construction often faces complex geological conditions, narrow space limitations, and strict control requirements on ground traffic and the surrounding environment. Therefore, the use of advanced tunnel support systems has become the key to ensuring construction safety and improving construction efficiency.
