Project Description
Fountain Slide has a long history of stability problems. The slope is bounded downhill by the Fraser River and uphill by a highway and a railway. This project stage focused on stabilization of a section of the railway that has suffered extensive damage to its retaining system.

With regard to possible solutions, several technical limiting factors had to be taken into account, the most important being the remote location and significant incli

Project Description

In 2009, the Swedish National Rail Administration presented a handbook with guidelines for the design of the load-bearing structure of rock tunnels. Following the merging of several transport administrations into The Swedish Transport Administration, an updated version of the handbook was required. In this version, the handbook comprised guidelines for railroad and road tunnels, as well as tunnel portals to: (i) provide advice on how regulations an

Project Description

A new motorway west of Stockholm linking the north and south side of Stockholm is under development – the so-called "Stockholm By-Pass" ("Förbifart Stockholm"). The new link is a 21 km long highway, of which 18 km is in tunnels. At the interchange of Lovön, four intake and exhaust air stations are planned, being in close proximity to the main tunnels and ramps. In this area, there is also a deformation zone going through the intake

Project Description

The Minneapolis-St. Paul International Airport (MSP) serves about 36 million passengers annually, via about 405,000 flights. On-airport parking provides about 22,900 parking spaces and is frequently at or near capacity. A parking ramp expansion has been proposed at Terminal 1-Lindbergh. It will be constructed over the north end of the Metro Transit Light Rail (LRT) station. The station (55 ft wide, 40 ft high, and 540 ft long) is constructed in the

Project Description
The Dannemora mine has been in production since (at least) 1481 until its first closure in 1992. The fact that the mine is very old, but also has been closed for some time, has influenced the infrastructure and mine planning during the earlier era of mining. At the re-start of the mine in 2012, several rock mechanical issues were identified, due to both the complex ore geometries and old mine planning, including: (i) position and stability of old drif

Project Description
In the context of a wine cellar extension project, a 20cm thick concrete slab is to be constructed on a soil reinforced by rigid inclusions. Itasca France has been called by the design office to verify the mechanical resistance of the concrete slab and assess its settlement under a uniform load.

The inclusions will be installed in a regular pattern. A 2D FLAC axisymmetric model represents the "unit cell". This model considers one inclusion,

Project Description

The Minnesota Department of Transportation (MnDOT) relocated a portion of T.H. 53 between Eveleth and Virginia, MN. The preferred alignment crosses the existing Rouchleau iron ore pit on a 1,100-foot bridge. Two abutments and one pier of the bridge will be founded on bedrock. Future iron ore mining adjacent to the alignment will create rock slopes up to 500 ft high. After mining, the new roadway will be atop a trapezoidal cross-section 300 ft wide

Project Description
Trevi Group has been involved in the design-build of a commercial building in Turkey in an area prone to liquefaction. The foundation of the building is located approximately 10 m below original grade, which still leaves about 10-12 m of potentially liquefiable sand underneath the bottom slab.

The owner proposed creating a grid of jet grouting cells—a common technique to improve liquefaction resistance in soil—with a spacing of

Project Description

Andra operates a surface repository in Aube (“CSA”, North‐Eastern France), where some of the concrete canisters containing low and intermediate‐level short‐lived radioactive waste are stacked in concrete structures, then filled with gravel (Fig 1). ITASCA Consultants SAS, together with EGIS Industries, has studied the mechanical behavior of the assemblies, in the framework of design and safety demonstration programs.</
