随着国家对基础设施建设投入力度加大,高速公路通车里程也日益延伸,有些软基路段由于施工技术欠缺或管理不到位等原因,导致通车后发生不均匀沉降、跳车等病害,影响行车舒适性和安全性。当前,对于高速公路运营中出现软基不均匀沉降的处治,最常用的做法是用沥青混凝土面层进行调平处理,但这种方法治标不治本,对于终年沉降不稳定的软基收效甚微,虽经调平、沉降仍在继续,会出现经常调平的现象。为了解决高速公路软基在运营中出现不均匀沉降的问题,建设者们尝试引进广泛
As the state invests heavily in infrastructure construction, the mileage of expressways is also on the rise. Some soft-foundation sections are not fully equipped or lack of proper management due to reasons such as uneven settlement, Comfort and safety. At present, the most commonly used method to deal with the uneven subsidence of soft ground during highway operation is leveling with asphalt concrete pavement. However, this method is a temporary solution to the problem that the soft foundation unstable throughout the year is ineffective , Although the leveling, settlement is still continuing, there will be regular leveling phenomenon. In order to solve the problem of uneven settlement of soft ground in expressways, builders try to introduce a wide range of
