Background
The geological disaster has the characteristics of wide influence range, strong destructiveness and the like, and the geological landslide is used as one of the forms of the geological disaster, thereby bringing great threat to the nature and the life and property safety of people. Due to the burst property of the geological landslide, people evacuation and property protection are difficult to carry out in time when the landslide occurs, so that early prediction and identification before the occurrence of the geological landslide are very necessary, more evacuation time can be strived for people before the occurrence of the landslide through accurate early prediction and identification, and further the loss of lives and properties is reduced.
The traditional geological disaster early warning method mainly adopts a method of monitoring data of a geological disaster high-incidence section in real time by arranging sensors and immediately giving an alarm if the monitored data reaches a preset threshold value.
However, the conventional geological disaster warning method has the following disadvantages:
1. the monitoring mode is single: a method of firstly setting a fixed threshold, then monitoring data and finally resetting the fixed threshold based on a monitored data feedback result is adopted all the time, and the monitoring means is too single;
2. early warning lag: if the alarm threshold value is set to be too high, disasters often come temporarily, and enough time is not provided for withdrawing the disaster-stricken personnel and rescuing the disasters;
3. the accuracy is low: if the alarm threshold is set to be too low, the early warning usually has larger deviation, and unnecessary manpower and material resources are wasted;
4. environmental factors are not considered: different geographical environments and different periods often correspond to different early warning thresholds, so accurate early warning cannot be performed more times.
Therefore, how to avoid the problems that the existing geological disaster early warning method is low in accuracy, poor in real-time performance and too single in monitoring means is still a problem to be solved urgently by technical personnel in the field.
