Planning slope stabilization actions

The risk posed by slopes may be taken as the intersection of slope hazards and vulnerability of elements at risk. Slopes deteriorate over time. The elements at risk also develop over time. Therefore, the slope risk evolves over time and proper slope maintenance or stabilization actions are needed to keep the slope risk within a tolerable level. This paper outlines a procedure for planning slope stabilization works considering changes of slope safety and elements at risk over time. An example is presented to illustrate the proposed procedure. The results indicate that as a slope deteriorates the risk of slope failure increases with time and may reach an unacceptable level at a certain time even though the elements at risk remain the same. In addition, the risk of slope failure may reach an unacceptable level due to a change of elements at risk. https://link.springer.com/chapter/10.1007%2F978-3-540-79846-0_25
