Problems solved by technology

[0003] However, some existing karst water inrush disaster magnitude assessment methods are not accurate enough for disaster assessment, there are large evaluation deviations, and the implementation is not convenient; and the existing karst water inrush disaster magnitude assessment methods are not suitable for disaster assessment. The time-consuming and complex operation of the evaluation process from start to finish slowed down the start time of the tunnel project
