Abstract: Some monitoring methods for geological hazards are introduced. General monitoring situation in mountainous geological hazards monitoring for Zhongxian-Wuhan Gas Transmission Pipeline is described, including relative regulations in distribution and allocation of hazard monitoring networks/points, monitoring period, monitoring grade/accuracy, and principle and method for data processing and monitoring prediction are given as well. Monitoring data from Huangcaopo palaeodebris flow constructions over the pipeline are analyzed, methodology in mountainous geological hazards monitoring and prevention is summarized and importance to monitor and prevent the geological hazards continuously is discussed.
