Long history of highway failures Designed and implemented an automatic data acquisition system Remote monitoring of landslide conditions This massive landslide has a history of creep movements interspersed with larger destructive movements. In March 1993, U.S. Highway 101 moved 35 feet (10.6 m). The landslide is 2,100 feet (640 m) long, 1,100 feet (335 m) wide at the highway, and rises 680 feet (207 m) above sea level. Oregon Department of Transportation stabilized it with an elaborate series of horizontal drains and a deep shaft. Landslide Technology designed and implemented an automatic data acquisition system (ADAS) in early 1994 with remote access via commercial telephone lines. The system was expanded by others and was again modified by Landslide Technology in 1995 to serve construction and long-term needs for 54 sensors including inclinometers, piezometers, and flow meters. The system is in full operation for ODOT to monitor the landslide conditions. Landslide Technology continues to provide reprogramming and trouble-shooting as needs arise. |
