在顶推施工中,箱涵框架与路基间产生的摩阻力会对路面结构造成破坏。文章结合工程实例对采用盾构法下穿高速公路,保证高速公路通行,所采用预加应力的路面加固方案进行简要介绍。
In pushing construction, the friction between the box culvert frame and the roadbed will cause damage to the pavement structure. Combined with engineering examples, this paper briefly introduced the scheme of using the shield method to wear under the expressway to ensure the freeway access and the prestressed pavement reinforcement scheme adopted.
