Multi-hole grouting, field tests to increase the efficiency of the grouting production process
Abstract: Time is a critical factor for tunnel construction and if grouting is required the time efficiency of the grouting procedure is essential for the overall cost of the tunnel construction. In this paper initial field tests of multi-hole grouting are reported and the possible time saving actions described. The test shows that the handling time of the equipment can be...

Regional-scale numerical stress model of the Stockholm area
Abstract: New metro lines are planned in Stockholm, comprising a total length of approximately 20 km with 10 new stations, mostly located underground. One of the new lines will pass under Saltsjön (a bay of the Baltic Sea) and through a major regional fault. The stress magnitudes and orientations around the fault are highly uncertain, and stress measurements are not practically possible near the fault....

Strategy for the permanent technical solution under the Lake Mälaren in the Stockholm Bypass Project
Abstract: The tunnels in the Stockholm Bypass Project connect the northern and southern part of this Nordic city passing through several regional fault zones and subsea passages. For instance, the passage under the Lake Mälaren, Sweden’s third-largest freshwater lake, and the regional fault zone in the Fiskar fjord constitutes one of the most challenging parts in this project. The uncertainties in this...
