Other Abstract

Mountain hazard is a major challenge to the construction of the Sichuan-Tibet Railway,thus risk analysis of landslides is significant to the disaster mitigation.In this study,a landslide risk evaluation method for linear project was proposed.The evaluation indexes were established by coupling parameters of environmental, trigger factors of landslide and exposure,property characteristics and resilience of the railway.The risk analysis model based on contribution weight approach was applied to the risk quantitative evaluation of Kangding to Nyingchi section of Sichuan-Tibet railway experimentally.Risk grading and mapping were done in GIS system.On this basis,the acceptable risk level of landslide hazard along the linear project was quantitatively analyzed.The results show that the railway line in the high and higher risk areas and unacceptable risk level areas is 131.13 km and 85.14 km,accounting for 10.7%and 8.47%of the total length of the line respectively.Therefore,the landslide risk of Sichuan-Tibet railway is better avoided in general.However,there is still room for adjustment in the alignment of some sections of the line in high risk areas.To prevent damage to the railway line,corresponding protection measures against landslide disasters should be carried out during the construction,operation and maintenance of the project.This method can provide reference for the risk management and route selection design of significant linear projects affected by the landslide disaster,such as Sichuan-Tibet railway.
