摘　　要：某地下大直径钢筋混凝土矩形箱涵地基不均匀性较为突出,为研究体系的抗震性能,基于试验资料考虑了土体的动力滞回特性及土-结构之间的接触特性,考察了三向厂址地震波作用下结构与地基的应力及伸缩缝位移的时域反应特性,方法及结论可为同类分析与设计提供参考。Since foundation inhomogeneity of an underground large-diameter reinforced concrete box culvert is obvious, it is necessary to study the anti-seismic performance of the foundation-structure system. In this paper, dynamic and hysteretic characteristics of soil and contact between soil and structure were considered based on test results. Stresses of structure and foundation soil layers, as well as displacements of contraction joints excited by site-related seismic waves were presented. Methods and results can be a reference for similar analysis and design.
