摘　　要：针对淮安立交地涵空间薄壁结构的受力特点 ,采用高精度六面体 8结点非协调单元 ,建立有限元模型 ,模拟结构的布置形式和细部特征 ,考虑闸室、地涵和地基的相互作用 ,分析边荷载、地涵水、运河水对立交地涵应力和变形的影响 ,对立交地涵的初步设计提出评价 。According to the action characteristics in the three dimensional thin wall structure of Huaian overhead crossing underground culvert, a high accuracy non conforming element is used and a precise finite element model is established to simulate the layout form and detailed characteristics of the structure. By considering the interactions among the lock chamber, culvert and foundation, the influences to the culvert stress and deformation from the side loads, culvert water and canal water are analyzed. In addition, the evaluation on the preliminary design scheme of the culvert and some reasonable suggestions are presented.
