Document Summary

Case study i. ii. iii. iv. v. vi. Excavated by machine/man, explosives are good for rock tunnels (we don"t have in cities) No limitation can use any path to access from point a to b. Basics of every structure (type of rock, soil, etc), texture, geological maps. Ground can be either rock or soil, once selected then you can move on to next construction steps. Rocks are made up of minerals which are part of 3 one of the rock types (igneous, sedimentary, metamorphic) Describe the texture of each area, which helps planning for construction. Software is used to simulate and model space for designing purposes. If the curvature of the path is too narrow then a machine cannot be used. Generally, the machine is ideal since it is automatic, cheap. In some cases, you can use both methods to complete a project. Damage can include tilting, cracks due to tunnel not being sound and geotechnical is inadequate.
