随着现代信息技术的迅速发展和需求的不断增加,目前对已建高速公路的改造已提上日程,很多道路需要对原交通工程设施进行改造,这就不可避免的涉及到横穿管道缺少的问题。如果采用传统的破复路面的方式则势必会影响交通,因此我们通过借鉴,将市政管网工程中的顶管施工技术引入到高速公路中来。文章通过普氏理论法和沟埋式埋管土压力公式对高速公路顶管施工中管道在路基内的受力状况进行了分析。 With the rapid development of modern information technology and the ever-increasing demand, the reconstruction of the already-built expressways has been put on the agenda. Many roads need to be rebuilt to the original traffic engineering facilities. This inevitably involves crossing the lack of pipes problem. If we adopt the traditional method of broken pavement will inevitably affect the traffic, so we learn from the municipal pipe network project in the pipe jacking construction technology into the highway. In this paper, stress of pipelines in subgrade of expressway pipe jacking is analyzed by Platts theory and earth pressure of buried pipe buried pipelines.
