STUDY ON STABILITY OF LOW EMBANKMENT OF HIGH TEMPERATURE PERMAFROST IN QINGHAI-TIBET RAILWAY

摘要

In order to satisfy the requirements of longitudinal inclination and abutment, low embankment which is lower than critical height of embankment arises in Qinghai-Tibet Railway at the south of Mountain Tanggula. According to the specifically condition, contradistinctive studies on ground temperature and deformation are put up on different engineering reinforcement to evluate different effect of permafrost protection. The results are concluded that effect of the embankment which is mounted large power thermosyphon and insulation plate is more favorable to protect permafrost.
