Abstract: The grillage method is an analytical method of space structure which can simulate the original structure well, and it owns characteristics of clear basic conception and low computing cost. Therefore, it is often applied to the design of the wider, skew, curved girder bridges. The basic theory of the grillage of boxing section was introduced in detail and the solid element of ANSYS was used to verify the practicability, with the hope to supply useful reference on the grillage theory and application to designers.

摘要： 梁格法是一种能较好地模拟原结构的空间结构分析方法,它具有基本概念清晰、计算费用低等特点,因此常应用于宽、斜、弯梁桥设计中。在这介绍了适用于箱型截面的梁格的基本理论,并用ANSYS实体单元验证方法的可行性,为设计人员对梁格理论的理解及应用提供了有益的参考。
