Effects of Climate Change on Landslide Slope Stability and Case Studies
In recent years, disasters caused by torrential rains and floods that exceed the planned scale are occurring in Japan due to climatic change. In response to it, Japan has been improving and reinforcing existing infrastructure to withstand more severe disasters. For example, in river projects, widening river width through channel excavation to increase flow capacity, and in road projects, lane widening and reinforcement of existing embankments to enhance the traffic network during disasters are occurring. At these project sites, there is concern that artificial topographic modification (changes in stress conditions due to excavation and embankment), which was conducted as a countermeasure, will affect potential weak surfaces in the ground, which, combined with the effects of increased rainfall caused by climate change, will destabilize the existing slopes and cause new slope changes (Kaneko in A collection of papers from the China Branch of Geotechnical Society, pp.161–168, 2018). In this wise, the demand for the assessment of landslide slope stability associated with increased rainfall caused by climate change and artificial modification is increasing; in this study, we examined a method for the assessment of landslide slope stability that takes into account the change in the strength of the slip surface associated with increased rainfall and artificial modification targeting a landslide area near a planned site for excavation of a river channel.
