Abstract:On September 5th, 2022, an earthquake with magnitude 6.8 happened in Luding, Sichuan Province, which caused severe geological disasters and brought heavy workload for rescue. It was urgent to find out the damaged roads in the disaster-hit area and assess the difficulty of rescue work. Multiple damaged roads were investigated and 507 damaged points were found. Characterized by large number, small scale, and continuous distribution, landslides and collapse accounted for more than 90% of the total damage. The severity of highway damage was positively correlated with the seismic intensity, while it was negatively correlated with the distance from fault zones and rivers. Under the combination of adverse impact, the degree of disasters on high way significantly increased. In some regions, even 92.5% roads were damaged. During the road reopening and recovery, a strategy of using the water transport resources in the reservoir area of Longtoushi and Dagangshan Hydropower Station to quickly establish five wharves and a green pathway to the epicenter was proposed. The reconstruction of the transportation network made full use of the water way instead of focusing on the road grade and indicator, aiming to improve the road resistance to natural disasters.
