Abstract In the construction of extra-long tunnels, the underground ventilation chambers are of great importance. This paper discusses an analysis of the cavern layout design for the Baotashan Tunnel as well as problems encountered in the construction of the ventilation chambers. Some adjustments were undertaken to facilitate convenience of construction. Furthermore, this paper addresses the merits and demerits of various schemes.
