Abstract:

During constructing the first class interprovincial road from the north Xinlin to Zhalantun in Inner Mongolia Autonomous Region, serious slope slide and collapse occurred at several places along the road. The current professional codes for road design and construction have not involved the road design and construction methods in frozen area at high latitude. Furthermore, little information can be found for reference. Based on the data collected from large scale investigation, the failure mechanism of the slope in this area is analyzed. Combined with the demonstrating project, the reliable construction procedure is suggested; and the corresponding calculation methods are presented. The research achievement can be for reference in designing and constructing roads in similar circumstance.

Key words: high-cold area, road foundation, highway slope, slide and collapse, stability analysis
