Tentative analysis on seismic safety evaluation of construction foundation and site

This thesis mainly studies the application of seismic safety evaluation methods of two kinds of high-rise construction sites,analyzes typical stratigraphic sites classification methods in Zhoushan areas by surveying site shearing wave velocity.Using soil liquefaction dynamic triaxial test,it analyzes liquefaction assessment methods by calculation.Research results show that: it is feasible to evaluate site seismic characteristics with reasonable methods;it is also necessary to strengthen seismic safety evaluation of high-rise construction foundation.
