本文先采用MIDAS建立整体模型，然后采用ANSYS软件建立主塔下塔柱局部模型进行空间效应分析。通过调取M IDAS中相应截面的内力并将其赋予局部模型，从而合理模拟局部模型的荷载及边界条件。分析了在荷载效应标准组合下下塔柱及横梁的应力分布情况并给出了横梁下缘出现拉应力的原因。结果表明，下塔柱混凝土大部分处于受压状态，压应力基本符合要求，锚固端局部出现了较大的压应力，但是范围很小。

MIDAS software is used to establish model for the whole bridge in this paper .Then ANSYS software is used to establish local model for spatial effect analysis of lower part of the pylon .By call-ing the forces of the corresponding elements from MIDAS for the local model of ANSYS ,the simula-tion of loads and boundary is reasonable .The stress distribution of the lower pylon and the beam un-der the effect of standard combination of load effects are analyzed .Reasons for occurrence of tensile stress at the lower edge of the beam are also given .The results show that most part of the concrete of the lower pylon is under compressed and the compression stress complies with the requirements . Large compression stress occurs at the anchor zone ,but just in a limited scope .
