Orientation about the project<\/strong><\/p>\n

Refoundation of the Vestbanen in Oslo with jet piles (J2-<\/p>\n

method). The building is today listed. Restrictions imposed by<\/p>\n

Byatikvaren was large and challenging.<\/p>\n

Foundation conditions<\/p>\n

The Vestbane building is founded with hewn foundation walls<\/p>\n

natural stone. The south wing is founded on mountains, while<\/p>\n

The arrivals hall and the north wing are based on wooden rafters.<\/p>\n

The raft was heavily attacked by rot in some places.<\/p>\n

The floor construction inside the access hall consists of vaulted ceilings.<\/p>\n

These are based on stone foundations on wooden rafts i<\/p>\n

crawl space and takes up floor loads and column loads from the structures<\/p>\n

above 1st floor level. Three of the foundations were characterized as i<\/p>\n

very poor constitution. The Vestbane building was partially affected<\/p>\n

major settlement damage, especially in the column and arch structures.<\/p>\n

Basic conditions<\/strong><\/p>\n

The ground consists of medium firm clay over mountains with assumed<\/p>\n

shear strength of 50kPa and bulk density of 20kN\/m2. The elevation varies<\/p>\n

from 0 to -12. It is shallowest to the mountains in the south with increasing depth towards<\/p>\n

north-west. The groundwater level is approx. at elevation + 0.26.<\/p>\n

\u00a0<\/strong><\/p>\n

Solution options<\/strong><\/p>\n

In the preliminary project phase, two reimbursement methods were considered: 1)<\/p>\n

Drill down steel posts on each side of the walls and then install<\/p>\n

ride through that spans from pile to pile. 2) Use Jet-pel<\/p>\n

the method.<\/p>\n

Selected solution<\/strong><\/p>\n

The project group recommended a solution with jet piles. The reason was<\/p>\n

based on the following points: Great predictability with regard to<\/p>\n

quality and execution. Minimal sentences and good in-situ control<\/p>\n

any deformations that may occur underneath<\/p>\n

the refunding works, so that corrective measures could be taken<\/p>\n

be implemented immediately. No vibrations\/shakes that can<\/p>\n

cause secondary damage to the building structure. It won’t<\/p>\n

reinforcements of the gray stone walls may be necessary. All<\/p>\n

the walls will receive direct support (contact moulding). Large portions<\/p>\n

of the works can be carried out from the outside of the building, with the exception of<\/p>\n

the internal foundations of the building. The execution will require small<\/p>\n

interventions in the constructions and will therefore be in line with<\/p>\n

the conservation decision. All interior work can be carried out from 1.<\/p>\n

floor plan. Great flexibility, low uncertainty\/risk.<\/p>\n

Sentences\/raises<\/p>\n

Accumulated sentences are not larger than +\/- 3mm. But with one<\/p>\n

stated measurement accuracy of +\/- 2mm is therefore minimal<\/p>\n

deformations of the floor and column construction.<\/p>\n","protected":false},"featured_media":2555,"parent":0,"menu_order":1,"template":"","meta":{"_links_to":"","_links_to_target":""},"class_list":["post-2551","referanser","type-referanser","status-publish","hentry","reference-type-dolomiti-refferanser-eng"],"acf":{"subtitle":"Referanse","title":"Nobels Fredssenter \u2013 Vestbanen, Oslo JETGRUNN","text":"","buttons":null,"image":"","video":"","focus_point":"end","style":"dark","type":"full","overlay_opacity":60,"enable_animation":false,"lottie":"","animation_opacity":60},"_links":{"self":[{"href":"https:\/\/seabrokers.no\/fundamentering\/en\/wp-json\/wp\/v2\/referanser\/2551","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/seabrokers.no\/fundamentering\/en\/wp-json\/wp\/v2\/referanser"}],"about":[{"href":"https:\/\/seabrokers.no\/fundamentering\/en\/wp-json\/wp\/v2\/types\/referanser"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/seabrokers.no\/fundamentering\/en\/wp-json\/wp\/v2\/media\/2555"}],"wp:attachment":[{"href":"https:\/\/seabrokers.no\/fundamentering\/en\/wp-json\/wp\/v2\/media?parent=2551"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
