Abstract
Stabilization of major soil masses using drainage tunnels
Highlights
Slope failures have been a major hazard to human life and the environment, with a recorded average of around 4700 fatalities per year from 2004 to 2016 (Froude & Petley, 2018) and 3270 fatalities in 2019 (Petley, 2020), excluding seismic triggered slope failures
The destabilizing effect of water plays a major role in triggering landslides and its control is one of the most effective tools for stabilization
This paper focuses on failures caused by water, rising groundwater, one of the main causes of the destabilization of large soil masses
Summary
Slope failures have been a major hazard to human life and the environment, with a recorded average of around 4700 fatalities per year from 2004 to 2016 (Froude & Petley, 2018) and 3270 fatalities in 2019 (Petley, 2020), excluding seismic triggered slope failures. For this reason, slope stabilization works in urban environment and along transportation routes is, and has been, a main issue in geotechnical engineering. Item 7 presents 3 case histories, where drainage tunnels were used to stabilize slope failures that were affecting important infrastructure projects.
