The invention discloses a geological disaster early warning system. The geological disaster early warning system comprises: a data collection module used for obtaining geological data acquired by a field monitoring instrument and transmitting the monitored data to a data processing module; the data processing module used for identifying the data in the abnormal state in the monitoring data and eliminating the data in the abnormal state; a data management module used for storing the processed monitoring data and basic data; a prediction analysis module used for calculating the processed monitoring data according to a preset BP neural network algorithm to obtain a geological disaster prediction value; and an alarm command module used for determining a corresponding disaster grade according to the disaster predicted value after the disaster predicted value exceeds a preset geological disaster safety threshold value, determining the corresponding evacuation information according to the disaster grade, and sending the disaster grade and the evacuation information to a mobile terminal for displaying. The problem is solved that the geological disaster early warning is not inadequately accurate in the prior art.

The invention discloses a device and a method for testing a deterioration mechanism of a crack-containing rock under water-rock interaction. The testing device comprises a base and a rock fixing device; the rock fixing device is fixed on the base; a thin film pressure sensor and a vibration sensor are arranged in the rock fixing device; a water deflector is arranged at the upper end of the rock fixing device; the water deflector is connected with a water supply device through a water pipe; both the thin film pressure sensor and the vibration sensor are electrically connected with a dynamic data collector; and the dynamic data collector is electrically connected with a computer. The testing method using the device comprises the steps S1-S6. Through the testing device and the testing method,the property and the structure of the crack-containing rock can be judged, and the probability that the crack-containing rock causes a geological disaster can be known; and the meso-structure and themechanical change process of a rock sample in the water-rock interaction process of the rock can be judged by quantitatively observing the stress strain and the micro-seismic change of the rock sample, and the deterioration process of the crack-containing rock under the water-rock interaction is visualized.
