Research of Tunnel Excavation Support Techniques

Abstract:

with the development of transportation infrastructure construction in the west, more and more excavation and support of all kinds of mountain tunnel been encountered in the project. Specific method of excavation and support should be ascertained according to tunnel types, size of section, depth of burial, wall rock types, hydrological condition, and construction machinery. Different excavation method will get different effect of wall rock stability .at present, there are variety of flaccid wall rock tunnel construction processes and methods, such as bench cutting method, ring cut method, CD method and CDR method, etc.
