The Effect Analysis of the Plate-Stone Berm Structure on Safety of Anti-Thawing of Roadbed in Qinghai-Tibet Railway

Abstract:

The plate-stone berm is an active cooling foundation to resist thaw. The Qinghai-Tibet Railway have been widely adopted the plate-stone berm to maintain the safety and stability of roadbed. Structure of the plate-stone berm have great effect on the safety of anti-thawing of roadbed. Different structure in one engineering measure cause different effect. Relying on the experimental segment in the region of Naquhe of Qinghai-Tibet railway (between DK1561+975～DK1562+530),the paper study the most safe anti-thawing structure by numerical analysis: The sunlit side height of plate-stone berm(dia. 20cm) is 1.1m, the sunless side is 1m. The sunlit/sunless side width is 6m/4m. The result is similar to practical test, which show that this method can use into engineering analysis.
