| 摘 要： | 水对边坡的失稳有很大的影响,在内蒙古西部干旱地区,往往由于集中降雨导致大量的路堑边坡失稳破坏,本文分析了降雨对边坡的不利影响,提出了考虑降雨作用的边坡稳定分析方法,并通过工程实例对该地区的边坡稳定性进行数值分析计算,其方法对干旱地区的路堑边坡设计及稳定性评价具有重要的借鉴意义.

| 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. |
