.... An extension of the facility is necessary to implement full-scale demonstration tests. Its construction started in 1997 and consists of the construction of a second shaft (1997–1999), and the excavation of a gallery 84 m long to connect the new shaft with the existing facility. The knowledge acquired since...

... ABSTRACT: In tropical areas, weathering is common down to several tens of metres, and can occur to depths of over a hundred metres. Tunnels and excavations in such areas are therefore very likely to encounter weathered rock. Weathering involves progressive weakening of the rock, ultimately...

As a soil stabilization tool, permeation grouting is most widely used for tunneling pre-support, excavation support, and utility and structural underpinning. Typically, sodium silicate (waterglass) is the preferred primary component, with either...
