SELECTION OF THE VERTICAL ALIGNMENT OF RAPID TRANSIT TUNNELS
The paper presents an abbreviated view of factors that influence selection of vertical alignment of rapid transit tunnels in an urban setting. The two principal factors relating to pre-existing site conditions are the geological setting and the impact of tunneling on adjacent structures. However, a wide variety of other influences makes itself felt, which includes geometric criteria based on train operations, overall route interaction, environmental and public policy considerations, and finally the total economic appraisal.
