现浇钢筋混凝土箱涵在南水北调工程中得到了广泛的应用,其结构设计的可靠性直接关系着整个调水工程的安全性和经济性.针对传统的结构力学方法在箱涵结构设计中未能充分考虑结构与地基间的相互作用,从而不能反映结构真实受力的情况,借助ANSYS软件,采用有限元法建立了箱涵与地基相互作用的二维模型,将计算得到的内力结果与结构力学法分析结果进行了对比,并对两种方法下的配筋结果进行了进一步的比较,比较结果显示有限元法更能反映结构整体的受力状态,可以弥补结构力学法对箱涵局部结构应力状态分析的不足,从而为合理的进行结构设计提供了有力的支撑.

The cast-in-place reinforced concrete box culverts are widely used in the South-to-North Water Diversion project,its structural reliability directly related to the safety and economy of the entire water transfer project. Aiming at the fact that the traditional method of structural me-chanics failed to take full account of the interaction between the box culvert structure and foundation and reflect the real force situation for the structure, with ANSYS software and finite element method , it established a two-dimensional model considering the interaction between the box culvert structure and foundation and compared the internal forces result of the analysis with the results of structural mechanics method, and made a further reinforcement result comparison under the two methods, the results indicate that the finite element method which better reflected the o-verall force state of structure can make up for structural mechanics method In terms of the local stress state for box culvert, so it provided a strong support, for the reasonable structural design.
