为提高我国高速公路季冻区软弱地基处理施工技术水平,本文首先简介我国季冻土产生机理与分布情况,并介绍目前常用处理软弱地基施工技术与冻胀路基防治处理措施,最后针对实际高速公路工程修建中季冻区软土地基处理进行施工,最后从施工后路基沉降检测分析施工后处理效果,对我国季冻区高速公路软土地基施工处理有积极意义。
In order to improve the construction technology of soft foundation in the quarry area of the expressway in our country, this paper briefly introduces the generation mechanism and distribution of the permafrost in our country, and introduces the current common treatment of the construction technology of the soft foundation and the treatment measures of the frost heaving embankment. Finally, Construction of mid-season frozen zone soft soil foundation construction for construction, and finally from the subgrade settlement after construction inspection and treatment of post-construction treatment effect, the construction of soft soil foundation in the seasonal frozen zone of our country has a positive significance.
