摘　　要：根据截锥壳理论 ,构造了一种位移和转角各自独立插值的四边形截锥壳单元 ,并编制了用于计算曲线箱梁桥的有限元程序。用该程序对一模型实验梁进行验算 ,理论值与实验值符合较好 ,说明该计算方法是切实可行的。Based on the conical shell theory,a quadrangular conical shell element,of which the displacements and rotations have their own shape functions respectively is constructed.Moreover,the computer program for calculating curved box-beam bridge is developed.There is a very good fit between the theoretical results with the experimental data,demonstrating the applicability of the method.
