Volume I “Details and construction processes” puts the emphasis on construction pro- cess technology as a constructive area of tunnelling. Support materials and construction,
Work on existing tunnels discussed in this article falls into one of three major categories, 1) lining a previously unlined tunnel, 2) partial liner removal, and 3) liner replacement. The parameters used in design and analysis will vary depending on the work being performed.
The broad coverage found in the Tunnel Engineering Handbook enables engineers to address such critical questions as how tunnels are planned and laid out, how the design of tunnels depends on site and ground conditions, and which types of tunnels and construction methods are best suited to different conditions.
Although tunnels are engineering structures, their structural analysis and calculation cannot be undertaken like structures above ground. Their load-bearing behaviour is decisively influenced by the construction method, also including for the tun-nel engineer the time factor as construction progresses. This factor is at least as significant
Conventional tunneling has become a method of choice in urban areas to construct complex underground structures such as metro stations, multi-track metro lines, rail crossovers, short road tunnels, and underground road ramps in order to avoid cut and cover construction with its impacts on streets, utilities, traffic, businesses and the public.
28 lis 2017 · A range of areas on the subject of tunnelling is covered in this book, including the following: soft-ground and hard-rock conditions; site investigation, parameter selection and design considerations; methods of improving ground stability and lining techniques; descriptions of various tunnelling techniques; safety and health considerations; and ...
In addition to discussing the construction of shafts and portals for tunnel access, mucking methods and tunnel haulage are discussed. The chapter on grout is longer because of the amount of material available and the importance of understanding grouting in tunneling. If the geologic material is weak, with
