摘要
2008年5月12日四川汶川发生8.0级特大地震,受此影响,宝成铁路成都局管段沿线产生地震次生地质灾害,直接威胁到铁路运营的安全。通过对铁路沿线次生地质灾害的震后排查,总结了地震产生的灾害类型,分析了地震的致灾作用和影响地震次生灾害稳定性的因素,在此基础上结合实际,提出防灾工程建议,具有重要的现实意义。
On May 12th 2008, an Ms 8.0 strong earthquake hit Wenchuan, causing serious disasters. It also resulted m varying degrees of damage of Baoji-Chengdu railway＇ s subgrade and ancillary facilities, and the safety of railway operations were threatened. The secondary geological casualties by earthquakes also adversed safety of the railway. It is of great realistic significance to investigate the railway secondary geological casualties after the earthquake, summing up the characteristics of earthquake damage and making proposals of disasterproof engineering.
