STUDY ON THE INFLUENCE OF EARTHQUAKE IN WUHAN AREA

The level of seismic effect and earthquake risk is rather low, and far intense earthquake can not be a main geological problem with engineerng projects in Wuhan area, but the earthquake resistance measures must be considerded in constructing urban lifeline and superior buildings. With the unceasing social-economic development in Wuhan, the influence of earthquake becomes gradually a rather important factor in engineering-geological environment evaluation. After the research on seismic ground motion attenuation regularities we make an evaluation of earthquake risk and analyze the dynamic parameters of soil layers in Wuhan area, and then point out there exist two main types of ground failures by earthquake in Wuhan area: liquefaction of sandy soil and collapse of soft soil layer, and their possible spatial distribution is put forward.
