%X Tianshan highway is located in high altitudes and cold region where freeze-thaw action is very strong,so it is important to take the influence of freeze thaw action into account when evaluating the side slope stability along the Tianshan highway. On the basis of statistical analysis of more than 100 slopes in Tianshan highway,a new rock mass rating system-TSMR,which is suitable for the slope stability evaluation of Tianshan highway,is established. With the RMR,SMR and CSMR rock mass rating systems,the correction coefficient ζ of slope height and condition coefficient λ of structure plane are adjusted by using mathematical statistics tools;and freeze-thaw coefficient δ is also introduced. At the same time,several pertinent supporting recommendations are proposed in TSMR system according to slope stability levels. Application results show that misjudgment rate of TSMR system is lower than that of the RMR-SMR system,thus the results are acceptable for slope stability evaluation in high altitudes and cold region.
