WRIGGLE SURVEY FOR HONG KONG METRO

The alternatives that have become available as a result of recent developments in survey methods and instrumentation were investigated. The method used for the metro that uses EDM tacheometry for taking the measurements which are then processed on a minicomputer is described. The initial route length of an underground railroad is 15 km, and the journey time for that distance is expected to be 40 minutes. It includes 26 km of tunnels and 6 km of overhead structures. The nominal diameter of the tunnels is 4.9 m. The advantages of the new method are outlined.
