严寒地区春融对膨胀土路堑边坡稳定性影响分析
摘要:结合我国北方某在建铁路工程实际情况,阐述了该地区膨胀土工程特性和路堑边坡破坏形式,针对本地区春融特点,分析了由春融引起的新开挖膨胀土路堑边坡的破坏机理,同时进行了气候变化与边坡滑塌的相关分析,总结推导了考虑春融特点的膨胀土边坡稳定性计算方法,提出了合理的工程措施建议。
Abstract:Combined with the actual situation in the construction of a railway project in the north of China,this paper expounds the correlation analysis of the area expansion soil engineering properties and cutting slope failure mode,for local district spring thaw characteristics,analyzes the new excavation by the spring thaw induced expansive soil slope failure mechanism.At the same time,the relationship between climate change and slope collapse is analyzed,with the consideration of spring melt characteristics of expansive rock slope stability calculation method,puts forward the reasonable engineering measures and suggestions.It has certain guiding significance to the construction of similar areas.
