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。
In order to study the seismic performance of a large-diameter reinforced concrete rectangular box culvert foundation, the dynamic hysteresis characteristics and soil-structure contact characteristics of the soil were considered based on the experimental data. The three-way site The characteristics of time-domain response of structure and foundation and the displacement of expansion joint under seismic wave can provide reference for similar analysis and design.
