Jet grout strut for deep station boxes of the north/south metro line Amsterdam: Design and back analysis

The new North/South metro line in Amsterdam contains several stations, some of which with an excavation depth of 30 m below surface. The design of these station boxes is very much determined by the adjacent historic buildings, high water table and the relatively soft soil. A lot of effort is put into minimising the settlements of buildings with...

Probabilistic analysis of soil: Diaphragm wall friction used for value engineering of deep excavation, north/south metro Amsterdam

The excavation of deep building pits often requires a check against failure by uplift of low permeability ground layers below excavation level. Whenever the weight of these soil layers is less than the pore-water pressure underneath, measures to resist buoyancy are to be considered. The measures most commonly adopted include: decreasing the...
