Abstract: Abstracts: Ground fissure disasters pose significant threats to the safety of residential areas and urban-rural planning in localized areas of Beijing. To analyze the impact of ground fissure activity on the dynamic response characteristics, patterns, and scope of affected sites, this study focuses on the Songzhuang ground fissure in Tongzhou district , a typical development area. Based on the field investigations, the study captured the development characteristics and influence scope of ground fissures and obtain key parameters such as the predominant frequency of the site through microtremor testing. Three dynamic analysis methods were applied to investigate the dynamic response characteristics and patterns of the ground fissure site. The results show that there is no obvious relationship between the excellence frequency and excellence period of the ground fissure site in Songzhuang, Beijing and the location of the measurement points. The ground fissure site exhibits a pronounced "hanging wall effect", with the Fourier Superior Frequency, the excellent cycle of the response spectra, and the peak intensity of Arias located in the hanging wall of the ground fissure generally exceeding those on the footwall. Additionally, the amplitude of the ground pulsation test is greater than that of the footwall in the area nearer to the ground fissure. The results of this study can provide valuable references for planning, construction, and seismic fortification of structures in the Songzhuang ground fissure development area.
