Risk Assessment Study on Long Oil and Gas Pipeline Construction-Induced Landslide Disasters

This paper developed a study of risk assessment for landslide disaster from oil and gas pipeline construction by systematically analyzing the characteristics of landslide bodies during the construction phase. Typical cases of slope landslides caused by pipeline construction are introduced and combined with the landslide disaster that occurred at the China-Burma oil and gas pipeline, supporting the following conclusions: the concept of risk is introduced by proposing adoption of semi-quantitative risk assessment methods. Summarizing the causal factors for the landslide disasters, during the China-Burma pipeline construction, and establishing a landslide risk evaluation indicator system. By evaluating the risk level at three typical geological disaster-prone zones, we confirm that evaluation results coincide with actual situation. Therefore, the proposed semi-quantitative evaluation methods have reference value for risk management of pipeline construction at geological disaster points (segments).
