Maastricht’s lowered urban Motorway

By 2016 Maastricht intends relocating no less than 80 % of the existing volume of traffic on the A2 urban motorway underground. The “Groene Loper” (Green Carpet) project represents one of the biggest construction schemes ever undertaken by the city in the south-east of the Netherlands. At present a double-deck tunnel with two bores is being produced – the first of its kind in Europe. The new tunnel is largely being built by cut-and-cover, in 24 m long sections on average, with traffic flowing right past the site and close to built-up areas.

Axis Deviations when producing Diaphragm Walls

At various construction sites the production accuracy regarding the axis deviations of diaphragm wall lamellae was investigated. After evaluating different series of measurements the normal distribution in accordance with Gauß was established as the suitable mathematical method for describing the frequency distribution. Under similar general conditions the determined parameters can provide the possibility for working out the anticipated axis deviations prior to executing a construction scheme.
