Abstract:

Slope stability is an ongoing issue in

hilly or mountainous terrains with clay

rich soil, constructed embankments,

fluctuating temperature, and changing

soil moisture conditions. Landslides

constitute a major geologic hazard,

occurring in all 50 states. Accurately

determining the shear plane depth in a

landslide is needed to devise an effective

remediation plan.

Slope inclinometer probing, the

current method for slope movement

analysis, is costly to install and monitor,

and it becomes ineffective in measuring

large lateral deflections. An economical

alternative to monitor slopes is electrical

Time Domain Reflectometry (TDR).

The cables used to implement TDR in

slope studies are inexpensive, simple to

install, and provide long-term

monitoring of slope movement.

Measurements take only seconds, a vast

contrast to the traditional time intensive

‘cable pull’ process of inclinometer

probing.
