Geology

Top Section: weathered marl

Bottom section: weathered sandstone / siltstone

Situation

In the first days of June 2013 heavy storms and intense rainfall hit the region of the upper lake of Zurich. Due to saturation of the ground and instable geological conditions, a landslide buried a long section of heavily travelled commuter roadway and railway along the lake. This landslide caused complete closure of the infrastructure.

Description

The department for underground construction initiated re-establishment and sustainable prevention of future similar incidents a few days later. To reach a quick decision and accelerate the construction, the department quickly involved local and regional partners.

Solutions discussed were rockfall barrier, manifold, or anchored TECCO®, the most favorable and ultimately chosen solution.

The upper slope section (marl) was protected and stabilized using a nailed mesh. The lower sandstone/siltstone section was covered with a drape to ensure that falling debris is kept close to the slope while being guided and deposited to the ditch.
