根据波动理论与子结构方法,本文对井塔结构的地震响应分析提出了新的计算模型与分析方法。该模型按照结构的实际受力状态取为层状地基土-竖井-井塔相互作用结构体系,其中对竖井及土体的作用采用Novak阻抗函数。将本文方法计算的结果与某地工程实测数据作了比较,表明本文所提出的计算模型与分析方法能够较为准确地反映该结构体系的受力状态。
According to wave theory and substructure method, this paper presents a new calculation model and analysis method for seismic response analysis of well tower structure. The model is based on the actual stress state of the structure as a layered soil-shaft-well tower interaction structure system, in which the Novak impedance function is applied to the shaft and soil. Comparing the results calculated by this method with the measured data of a certain place, it shows that the calculation model and analysis method proposed in this paper can accurately reflect the stress state of the structural system.
