摘　　要：该文采用结构有限元计算方法,以一座斜交弯梁桥为工程背景,利用ANSYS软件建立该桥计算模型。运用参数变异法,计算在恒载和预应力作用下斜交弯梁桥与弯梁桥及直线桥的力学行为的各自特点,对比分析其之间变化的规律及成因,可供工程设计和施工部门参考和借鉴。The skewed bending bridge model is set up by using the calculation method of the structural finite element and ANSYS software under the background of a skewed bending bridge.It is to calculate the mechanics behaviors among skew bending beam,curvature beam bridge and straight beam bridge under the constant loading and prestressed action by the parameter variation process.It is to contrast and analyze the law and cause of the variation able to be referred for the engineering design and construction departments.
