下穿高速公路顶推箱涵设计与施工关键技术

在地质条件为软弱土和液化土、地下水位较高、箱涵绝大部分在地下水位以下等情况下,郑州至开封高速公路箱涵成功地下穿京港澳高速公路分离式立交桥,为我国在复杂情况下下穿高速公路大型斜向箱涵顶推提供了丰富的设计和施工经验。

Design and Construction Key Technologies of Pushing Box Culvert Passing through Beneath Expressway

The box culvert of the expressway from Zhengzhou to Kaifeng passed through successfully beneath the expressway from Beijing to Hong Kong and Macao in complex situations,such as the soft soil and liquefaction of soil,higher water table,groundwater above the box culvert in most cases,etc,which provides a wealth of design and construction experience to push large diagonal box culvert passing through beneath expressway in complex situations in China.
