Determination of the Cross Section of New Krivelj's River Tunnel
New Krivelj’s river tunnel will be made through very bad surrounding for production and stability of the premises, both, during development and for the period of use. During the construction of underground objects in weak environment, in this case the future tunnel (collector), it is necessary to pay attention to the process of creating and supporting. Shape of hydraulic tunnel cross section depends on several factors, among which are: the static condition of tunnelling linings, hydraulic working conditions of the tunnel and conditions under which will be constructed Criteria for defining the final cross section of the tunnel, which will meet all requirements, will be presented in this paper.
