Topic Information

Dear Colleagues,

Among all the geological disasters (GDs), collapses, landslides, and debris flow are the most serious. The prediction of geological disasters is the most effective means to reduce casualties and property losses. However, early identification and warning technology for collapses have been difficult to achieve effectively. Therefore, the scope of this research topic is about the quantitative identification of dangerous rock, the risk assessment of landslide instability precursors, the quantitative model of a movable solid source in a debris flow source area, the application of research on new monitoring and early warning technology systems, and the corresponding control and reinforcement measures. In addition, this Topic also welcomes papers of remote sensing technologies (e.g., InSAR, LiDAR, and multispectral/hyperspectral imagery) in early detection of precursory deformation, large-scale hazard mapping, and real-time monitoring of landslides, rockfalls, and debris flows. Submissions exploring how advanced remote sensing approaches can effectively bridge field-scale observations and regional risk assessment are particularly encouraged. We cordially invite relevant scholars to submit their research findings to the article collection of this Topic, which will hopefully improve the early warning technology of GDs and serve as a platform for the exchange of knowledge and the discovery of new innovations. The subtopics include but are not limited to the following:

  • Rock dynamics and failure precursor of rock collapse.
  • Quantitative dynamic damage identification of unstable rock or rock landslides.
  • Analysis of the causative mechanism and disaster-causing factors of GDs.
  • Risk and stability assessment method for GDs.
  • Quantitative model of movable solid source in debris flow source area.
  • Application research of new monitoring technology for GDs and establishment of the early warning index system.
  • The corresponding control and reinforcement measures for GDs.

As is already known, some currently stable landslides may have been activated in the past along a pre-existing sliding surface and reached the residual strength there, as a consequence of high-cumulative displacements. After a fairly long period of quiescence, these landslides can reactivate due to a temporary increase in destabilising forces capable of mobilising the residual strength along the same sliding surface again. Some recent studies have suggested that, under certain conditions, the strength mobilised upon reactivation may slightly exceed the residual value and then decay towards the latter as the displacement progresses. Regarding this matter, many previous studies have hypothesised that some geotechnical variables could affect the recovered strength more significantly: the length of the ageing time, the vertical stress, the stress history, and the speed with which the reactivation occurs. The aim of this research is to confirm whether such recovery of strength upon reactivation is possible and which geotechnical parameters have the greatest influence on the process. To this end, laboratory tests were carried out with the Bromhead ring shear apparatus on normally consolidated saturated samples of both natural soils and clays provided by industry (bentonite and kaolin). The coupling effect of the ageing time, the vertical stress, and the reactivation speed on the mobilised strength upon reactivation were investigated, starting from a pre-existing residual state of these samples. Within the limits of this research, the results seem to confirm that all three geotechnical variables are influential, with a greater impact on the reactivation speed and, subordinately, on the ageing time for long quiescence periods. Therefore, it is concluded that a quiescent landslide could show a reactivated strength slightly higher than the residual value if the destabilising action could arise with a certain rapidity. Conversely, if the destabilising action occurs very slowly, the mobilised strength could correspond to the residual value. The experimental results of this research may find some application in the design of strengthening works for a stable quiescent landslide that could experience a fairly rapid increase in destabilising actions, such as in the case of seismic stress, morphological modification of the slope, or a rising water table.
