CONSTRUCTION PLANNING OF TUNNELS FOR WATER RESOURCES DEVELOPMENT

Abstract

Tunnels are required in most water resources projects and the future ties in driving tunnels at a repaid rate for many of the proposed schemes. The use of highly product .ve equipment and method has resulted in tunnels being driven more economically and speedily. Due to varying geology and topography, the construction method and equipment adopted on each tunnel are unique. The task of proper planning of tunnels becomes all the more difficult for want. of published data and literature at one place in such form as to provide material for easy ref-erence. Therefore, all aspects of tunnel construction in rock have been reviewed in detail and an attempt made to provide data and lay broad guide . Lnes for ease In planning of tunnel construction for Water ,resources development schemes in developing countries.
