Based on the index scoring method, the semi-quantitative method for assessment of pipeline geological disaster risks calculates the relative risk of a disaster by investing and assessing the objective existence state of index in accordance with pre-determined scores and weights, and meets the requirements of risk prioritizing and ranking at the geological disaster investigation stage so as to guide the development of risk control planning. A geological disaster risk semi-quantitative assessment system and risk grading standards both of which are applicable to oil and gas pipelines have been established. What has been developed also includes the pipeline geological disaster risk management system software, which integrates the risk semi-quantitative assessment technique based on the index-scoring-method, and other techniques such as information management and risk management, and thus provides a platform of information, technology and management for the management of pipeline geological disaster risks. This method has been used for a unified risk assessment of more than 3300 disaster points along the oil and gas pipeline, and satisfactory evaluation results are obtained, thus providing an important basis for the development of planning of pipeline geological disaster risk remediation.
