... Wendlingen to Ulm as part of the major DB project Stuttgart–Ulm. In 2012, the tunnel was tendered by the DB AG for construction by conventional methods with shotcrete support, but a bid for the Boßler Tunnel was received from the consortium Porr, Hinteregger, Östu/Stettin and Swietelsky with an alternative...

... Abstract In the underground construction of tunnels, high precision of convergence and settlement measures are necessary, and the employment of the total station can attain this goal. The resultant errors of the precision of the total station are evaluated, considering its linear and angular...

... Abstract The Jansen Project is a greenfield potash mine development being undertaken by BHP in Saskatchewan, Canada. The project, which remains subject to sanction by the BHP Board for full construction and execution, includes a pair of shafts which have been sunk to a depth of approximately 1...

... Abstract Construction of metro foundation pit is one of the most critical phase as it easily cause accident in the process of metro construction. Foundation pit is complexity and ambiguity, which has made such fuzzy mathematics very attractive to the construction project. The fuzzy...

... are that the temperature influence of construction extends 5 m into the surrounding rock mass, and that insulation layers within the tunnel lining, and cooling systems within the tunnel, should be considered in tunnel design in permafrost regions. 1 Introduction Underground excavation design in permafrost conditions...

... Introduction With the development of the construction technology for super-large shield tunnel, shield tunneling has become one of the main construction methods for the river-crossing tunnels. Even though shield tunneling possesses the characteristics of fast construction speed and high security, but issues...

... Abstract Rockfall mitigation designs based on previous experience or vendor assurances may not prove amenable to cost-benefit based design. A purely conservative approach to rockfall mitigation may prove very costly in large pit slopes and major construction projects in deep valleys or other...

... Abstract The design and construction of a road tunnel must include variables, parameters and components related to the type and use of the tunnel. If in the vicinity of the project there is another tunnel and infrastructure with high sensitivity, the design has a greater complexity. The road...
