低路堤公路不但能够节约耕地资源、减少土方量、降低工程造价,实现公路建设的可持续发展,而且能够提高公路的行车安全、使道路与周围环境和谐一致。文章以江北沿江高等级公路(南京段)工程为依托,结合弹性层状体系理论,利用BISAR程序研究了低路堤基底固化层的作用,研究结果表明,基底固化层能够提高路基整体的强度,减少交通荷载引起的工后沉降,并为水系发达区域的机械碾压施工提供工作面,为今后低路堤的设计和施工提供了一定的依据。
Low embankment road not only can save arable land resources, reduce earthwork, reduce project cost, realize the sustainable development of highway construction, but also can improve the driving safety of the highway and make the road harmonize with the surrounding environment. Based on the engineering of Jiangbei Yanjiang Expressway (Nanjing Section), combined with the theory of elastic layered system, the effect of basement solidified layer on low embankment is studied by BISAR program. The results show that base solidified layer can improve the overall strength of embankment and reduce Traffic load caused by the post-construction settlement, and for the developed areas of the water system to provide mechanical rolling construction work for the future design and construction of low embankment provides a basis.
