Abstract四川境内成昆铁路沿线泥石流活动频繁,严重危害和威胁着铁路安全。泥石流致灾原因如下:对泥石流认识不足,造成漏判、错判,从而处置不当;桥梁结构设计欠妥,在泥石流流通区设中墩;桥涵孔径过小,泥石流排泄不畅;建筑物位置不佳,排导设施不良;傍河铁路,对泥石流的间接危害重视不够;人类不合理的经济活动,加剧了灾害的发生。
Other AbstractThe debris flows disasters along Chengdu-Kunming Railway in Sichuan Province are frequent and serious. From July of 1970 to the end of 1988, about 370 people died from debris flows; 15 stations suffered from them,among them, 2 stations were destroyed and had rebuilt; 3 trams got deraiied;the tunnels were silted up for six times;2 railway bridges were destroyed,and trains broke off about 60 times and more than 1 ,200 hours.This railway is the main line where debris flow disasters are most serious. The main damages caused by debris flows are as follows:destroy bridges,turn over the trains,block up culverts, silt up stations, railway, tunnels, destroy raod-bed and facilities etc.The disaster causes for debris flows are; 1. Natural conditions are adverse,debris flows develop strongly. 2. The understanding to debris flow is not enough,thus missing or mistaking in discrimination of debris flow. 3. Owing to wrong choice of bridge structure, the bridge piers are endamaged. 4. The bores of bridges and culverts are too small so that drainage is difficult. 5. The drainage works are not proper. 6. The secondary disasters of debris flow would not be paid an attention. 7. The human unreasonable economic activities aggravated the disasters.
