浙赣线K402+990～K403+680地段位于上饶站以西18公里,坑口车站西岔外(约1公里);属小煤窑路基病害地段。历年来曾多次产生路基坍陷,长期影响线路稳定,成为浙赣线较大的路基隐患。我段通过长期的监测采取了相应的防范措施,本文就此谈谈我们粗浅的认识及体会。 Zhejiang-Jiangxi line K402 +990 ~ K403 +680 Lot is located 18 kilometers west of Shangrao station, Hang Hau station outside the west fork (about 1 km); is a small coal-based subgrade disease lots. Over the years have repeatedly subsided subgrade collapse, long-term impact on the stability of the line, as the Zhejiang-Jiangxi line greater hidden dangers. I have taken corresponding preventive measures through long-term monitoring. This article will talk about our superficial understanding and experience.
