摘要
下穿京珠高速公路的钢筋混凝土顶进箱涵是郑州至开封城市通道项目的关键工程,目前,该箱涵宽度为亚洲第一.采用有限元方法对管棚支护下顶进施工的箱涵结构进行了多种工况下的受力分析,结果表明本设计具有有效性和合理性.
Reinforced concrete box culvert advanced under Jingzhu highway is the key engineering of the city-routeway project between Zhengzhou and Kaifeng, and it is the largest box culvert of Asia. The article applied finite element method to analyze the stresses of box culvert structure advanced in pipe-roof under various operating modes, and the results show that the validity and rationality of our design.
