| Abstract: | Based on COMGIS(component object model GIS) technique,the simulation of site earthquake influence field under scenario earthquake can be generated by calling SHAKE91,a commercial program to analyze seismic response of level layered site.Then,seismic hazard for sandy soil liquefaction can be evaluated by ANN(artificial neural network) model which is modularized under VB by importing ANN toolbox from Matlab.There,the analytic results from ANN model can be simulated spatially by GIS,and the spatial distribution of site liquefaction potential also can be graphed. |
