摘要
随着高速公路的大量建设,在冻土区域修建公路时,由冻土冻胀翻浆所引起的道路建设问题日益突出,已严重影响到工程技术人员对工程质量和进度的把握与控制。由于冻土的特殊工程特性,导致了防治技术的特殊性。文章介绍了冻土的组成及形成、冻结力的影响因素,并针对其工程特性,在施工上提出了相应的防治技术。
With a large number of highway are being constructed,the road construction problem caused by frost heaving-boiling is increasingly outstanding in froze soil areas,which has seriously influenced the construction quality control and schedule control from engineers and technicians.And the special engineering properties of froze soil lead to the special properties of control technology.The paper introduces the composition and formation of froze soil and the influencing factors of freezing force,then proposes corresponding control technologies according to engineering properties.
