用有限元FEMⅡ程序分析槽箱受力状态

运用综合性有限元结构分析程序FEMⅡ,以洛河渡槽槽箱为例,建立力学模型,对槽箱进行了各种荷载组合作用下的结构内力、应力及变位分析。搞清了槽箱各个部位在各种荷载组合作用下的受力状态,预测了结构可能出现裂缝的部位及方向,对于结构尺寸的选择及配筋设计具有重要意义。此外,还将有限元分析成果与常规设计结果进行了比较。

Forced States of Box-aqueduct Structure Analyzed by FEME

The mechanical model of the Box-aqueduct of LuoHe aqueduct was established and the internal forces, stresses and deformations for the Box-aqueduct under various load combinations were analyzed by FEM H, a program for finite element structure static analysis, and the position and direction of the rift that may be occurred at the face of the structure were predicted in this paper. The results have been an important significance in the choice of the structure dimension and the reinforcement. Also, a comprison between the results and the normal designs was made.
