Année d’installation

2014

Situation de départ

During the latter half of 2013, the region had unseasonably high rainfall which led to several slope instability cases along the route. The majority of instabilities occurred as rock falls and superficial slides. The project was seen as an emergency work to develop a timely solution to the problem to ensure the pass could remain open to traffic while not compromising safety. Furthermore, in keeping with the heritage of the route and the surrounding environment, aesthetically pleasing and environmentally friendly solutions were required.

Géologie

Sedimentary rocks, highly folded. It falls under the Malmesbury Group of rocks and consists of pale-weathering massive quartzites, subgreywacke, conglomerate, dark slate and phyllite. The soil consists of 18-24% clay. The site consists predominantly ML (acc. USCS) materials.

Description

A key feature of the solution was to significantly improve surface and underground drainage. Geobrugg's RUVOLUM® software was used to ensure the correct system materials/products were chosen and that these effectively integrated with the overall geotechnical solution. A combination of TECCO® System and TECMAT® erosion control material was used to cover the area.
