摘要
结合南水北调工程中的某新型上承式预应力混凝土拉杆拱渡槽,运用三维有限元软件MIDAS/Gen对该渡槽的支撑结构——上承式预应力混凝土拉杆拱在各种工况下的内力分布规律进行分析,较全面地评价了其整体受力性能。
A new type of structure system-top supported pre-stressed tie-arch aqueduct was used in the South-to-North Water Transfer Project. The law of the stress distribution of the top supported prestressed tied arch under various loading conditions are analyzed with 3D FEM software MIDAS/Gen,and the unitary stressed performance are evaluated in the round.
