LANDSLIDE MONITORING AND EMERGENCY NOTIFICATION SYSTEM CEDAR HEIGHTS SUBDIVISION, COLORADO SPRINGS, COLORADO

摘要

The Cedar Heights community is a private subdivision located in the foothills west of Colorado Springs, Colorado. At one location within the subdivision, approximately 10 meters of fill was placed over an existing landslide during road construction in 1980. During extended wet periods in the spring of 1995 and the spring of 1998, the landslide reactivated through the road fill material. The road was repaired after the failures to re-establish the roadbed. A geotechnical investigation during the summer of 1998 identified two separate slide surfaces below the road. Subsequent to the investigation it was determined that the landslides would not be stabilized. Therefore a real-time landslide monitoring and emergency notification system was installed to provide for the safety of the public which would traverse the landslide. The design of the landslide monitoring and emergency notification system is presented in this paper.
