强夯法作为提高地基承载力的一种有效施工方法,能有效防止高寒阴湿地区路基沉陷等早期破坏,本文就结合夏河机场路二级公路改建工程施工中对沿线高填方路基、填挖结合部等进行强夯处理实施实例,通过工程现场试夯,对夯击数、超静孔隙水压力进行检测,研究了强夯法在二级公路改建中的应用及其相应施工工艺及检测方法,对今后二级公路改建中强夯法的设计与施工提供了理论依据。
Dynamic compaction as an effective method to improve the bearing capacity of the foundation, which can effectively prevent the early subsidence and other subsidence in humid and humid areas of early damage, this article combined with the construction of the second-tier highway Xiahe Airport Road to fill the high embankment along the embankment, Combined with the implementation of dynamic compaction and other examples, through the on-site test rammer, the number of dynamic impact, the number of excess pore water pressure to detect the dynamic compaction method in the reconstruction of secondary roads and its corresponding construction technology and testing methods , Which provides a theoretical basis for the design and construction of dynamic compaction method in the reconstruction of the second-level highways in the future.
