摘　　要：通过对某桥匝道桥部分立柱进行温度应力分析,利用ANSYS软件,建立有限元模型,在日照温差和骤变温差工况下计算了立柱的应力状态,分析了裂缝的可能成因,并提出了相应的建议,从而减少桥梁立柱裂缝的产生。Through temperature stressing analysis on annular part of a bridge, the paper establishes finite element mode using ANSYS Software, and calculates stressing states of the column under the situation of sunshine difference in temperature and suddenly changed difference in temperature, it analyzes possible reasons for cracks, and also propose relative suggestions, so as to reduce cracks in vertical column of bridge.
