Engineering a landslide

Article Abstract:

An earth-reinforcement project costing $1.75 mil on a section of U.S. route 43 south of Florence, Ala., using grouted piles that provides load transfer across the failure plane of the slide has stopped the movement of the slope as suggested by the initial data from the in situ earth-reinforcing techniques wall system. The project was completed in mid-September, 1994 by the Nicholson Construction Co., Alpharetta, Ga.. The wall was fitted with $100,000 worth of instruments, which will provide invaluable data in the future.

A landslide of litigation

Article Abstract:

The Stonehill Drive project successfully stabilized a landslide at the Southern California coastal area. This landslide was reactivated by a street expansion project. The landslide project utilized a design with five horizontal rows of post-grouted tiebacks, using bundled strand anchors with a double corrosion-protection system. It brought the landslide rate considerably down from the original level of 0.003 in./day in 180 days. The project resolved various issues related to legal liabilities.

Erosion-control blanket saves the day during landslide

Article Abstract:

Hydro-Blanket, a mechanical bonded fiber matrix (BFM) produced by Wood Recycling Inc, was used by Karleskint-Crum Inc (KCI) to control soil erosion in the drainage system installation and slope regrading at the Avalon Canyon near Daly City, CA. KCI used the product to treat the steepest terrain and was satisfied with the results although it costs more than the traditional BFM applications at $1.23 per kg.
