HISTORIC SLOPES & EMBANKMENTS FALILURES

SLOPES & RETAINING STRUCTURES

The Slopes and Retaining Structures are a common and complex part of highway structures and public/private properties. Both retaining systems are subjected to stresses (gravity, seepage and earthquake forces) acting on the soil mass that tends to cause downward and outward movements. Slopes or retaining structures failures can occur rapidly or slowly in many different types and forms. Regardless of fault type or form, the fact is that these can cause huge economic losses that result in both direct (repair or replacement and maintenance) and indirect (loss of industrial, agricultural and forest productivity, loss human and animal lives, tourist revenues, and interruption of transportation systems) costs that affect the public and private properties, like was the massive landslide at Thistle, Utah at 1983. This landslide dammed  the Spanish Fork River, obliterating U.S. Highway 6 and the main line of the Denver and Rio Grande Western Railroad causing damage and loss of total costs that exceeded $400 million.


Regular inspections and maintenace are essential for the continued stability of slope and retaining structures. However, sometimes recomendations for maintenance not followed after their constructions.


A Structural Health Monitoring System will help the owners to monitor their properties remotely (24/7 of year) during and after construction of them, providing and improving their construction monitoring program, long term monitoring and maintenance program, and safety program providing warning signs.


Below some of the sensors used to monitor the behavior and performance of slopes and retaining structures:
