EXPERIMENTAL STUDY OF SUBSIDENCE DEFORMATION OF AEOLIAN SOIL AROUND FUXIN CITY UNDER SEISMIC LOADS

Seismic settlement of ground soil due to seismic loads is an issue of geotechnology. Seismic settlement tests of Aeolian soil in west of Liaoning province were conducted under the earthquake loads exceeding that would happen with 2 and 10 percent of propability in the future 50 years and in constant amplitude loads. The effects of vibration cycles, dynamic stress amplitude and moisture contents on the seismic subsidence coefficient of Aeolian soil are evaluated. An empirical formula of Aeolian soil's seismic subsidence ratio is obtained. The subsidence values of Aeolian soil field under the seismic loads and constant amplitude loads are predicted according to the layerwise summation method and its seismic subsidence is assessed. The research results provide a reference for the seismic design of Aeolian soil region in west of Liaoning Province.
