| 摘 要： | 在软基地区修建高速公路临时便道,需要克服高填方带来的差异沉降过大和新老路基搭接处产生的拉裂破坏问题.泡沫混凝土具有比重小、强度高、透水性低、工期短、固结自立等特点,选择其作为路基填筑材料能够切实解决高速公路临时便道施工中遇到的难题.鉴于此,结合具体工程实例,介绍泡沫混凝土在软基地区高速公路临时便道工程中的应用,可为相关项目施工提供参考.

| Abstract: | The construction of temporary road of freeway in soft foundation area needs to overcome the problem of large differential settlement caused by high embankment and the tensile failure at lap joint of new and old subgrade. Foam concrete is of the characteristic of small proportion, high strength, low permeability, short construction period, consolidation self-reliance, etc., and selecting it as subgrade filling material can effectively solve the problems encountered in the construction of temporary roads of freeway. Given this, combined with engineering examples, the paper introduces the application of foam concrete in temporary road project of freeway in soft foundation area, which can provide references for the construction of related project. |
