Abstract: In order to accurately and quickly evaluate the hazardous impacts of typical geological disasters occurred along oil and gas pipeline, after analyzing the harm forms, hazardous factors of three kinds of geological disasters (i.e. collapse, landslide and debris flow) are identified and classified, and relative weight of each factor is calculated. On this basis, the hazard assessment system of typical geological disasters along oil and gas pipelines is built. The influence grading standards and scoring criteria for hazardous factors and risk evaluation criteria are discussed in detail. Considering the susceptibility of geological disasters and pipeline vulnerability, simple and operable index system is selected for risk assessment. The evaluation method is applied in a case of pipeline disaster. The results show that the hazard assessment technique of typical geological disasters along oil and gas pipeline is highly operational and practical. The research results are very important for guiding risk control of pipeline construction with potential geological disasters.
