Abstract

The intensive ground movement of seismic region was an essential factor in causing ground damages. Damages in historical events signified that the extent of destruction not only conformed to the epicentral distance but also related to geomorphology, soil type and ground structure. Different combination of ground lithology may reflected directly the enhancement and attenuation of seismic wave during its propagation and it had also dominating influence on ground movement, different damages and seismic excitation of the same ground. Hence the amplitude and type of seismic response spectra were determined. In this paper, ground movement and damage feature on geomorphology units of various ground as well as the influence of seismic wave field on earthquake damages were analyzed by seismic ground response. Site zoning was carried out based on the types of response spectra.

Surface Damage of Tangshan Earthquake and Characteristics of Response Spectrum of Ground Movement

The intensive ground movement of seismic region was an essential factor in causing ground damages. Damages in historical events signified that the extent of destruction not only conformed to the epicentral distance but also related to geomorphology, soil type and ground structure. Different combination of ground lithology may reflected directly the enhancement and attenuation of seismic wave during its propagation and it had also dominating influence on ground movement, different damages and seismic excitation of the same ground. Hence the amplitude and type of seismic response spectra were determined. In this paper, ground movement and damage feature on geomorphology units of various ground as well as the influence of seismic wave field on earthquake damages were analyzed by seismic ground response. Site zoning was carried out based on the types of response spectra.
