- Abstract:
- The mud—rock flow is the main geological disasters to the highway at Tianshan area．
Through the investigation of damaged road segment by mud—rock flow，the characteristics of
mud—rock flow and the interaction of mud—rock flow with highway subgrade are analyzed，the
numerical coupling model of the interaction is developed，the coupling interaction of mud—rock
flow and prevention structure is simulated by numerical simulating software．The results show
that the coupling interaction is restricted by the scale of mud—rock flow，and the most likely
location of the damaged subgrade is the section that is directly faced the mud—rock flow．1 tab．
