A GUIDE TO SITE INVESTIGATION PROCEDURES FOR TUNNELS

The report is a general guide to site investigation for bored and cut-and-cover tunnels and associated shafts and portals, constructed for sewers, aqueducts, transport and other services. It outlines the objectives of a site investigation for a tunnel and reviews the steps required in carrying out and reporting the investigation, the methods that may be used, and the considerations that must be borne in mind. Emphasis is placed on the importance of good core recovery and the full description of strata, the thorough examination of ground water conditions, and the value of in situ tests and trials. The value of a staged approach to the investigation, and the importance of full reporting of each stage of the work with full communication of results and conclusions to all interested parties, are also stressed. /Author/TRRL/
