摘要
山区公路高边坡开挖实质为岩体卸荷,坡面水平位移向临空面发展,引起边坡内部应力调整重分布,可能会导致边坡失稳,需及时予以防护和治理。以都匀至香格里拉高速公路K34+340-K40+800段工程设计为例,选取了其中K34+725~K35+160深挖路堑边坡,介绍了高路堑边坡施工中出现的问题及采取的处置措施,总结了山区高速公路深挖路堑边坡的处置技术,可为山区高速公路的建设提供一定的指导及借鉴。
The excavation of high slope in mountain expressway is the unloading of rock mass,and the slope surface displacement develops towards the empty surface,which causes the adjustment and redistribution of the internal stress of slope,and may form the hidden danger of safety,which needs to be protected and treated in time. Taking the engineering design of K34+340 ~ K40+800 section of Duyun to Shangri-La expressway as an example,K34+725~ K35+160 deep cut slope is selected,the problems in the construction scheme of high cut slope and the treatment measures taken are introduced,and the treatment technology of different lithologic slope of mountain expressway cutting is summarized. It can provide guidance and reference for the construction in mountain expressway.
