Abstract:
The fast and safe construction of deepburied long tunnels depends on such major constraining factors as driving length, highpressure ground water, high ground stress, high ground temperature and construction ventilation. Furthermore, the fast and safe construction of deepburied long tunnels is closely related to the construction conditions of the specific tunnel projects. On basis of the construction of the west contract section of the auxiliary traffic tunnels of Jinping hydropower works, the author analyzes on the major factors that constrain the fast and safe construction of deepburied long tunnels and investigates on the execution plans to overcome these constraining factors. The author also studies on the key technologies for fast and safe constructions of deepburied long tunnels, which include equipment matching, deep straighthole cut blasting, fast supporting and construction organization.
