Abstract: In this paper, a staructure stability evaluation for the engineering reconstruction site in Yellow River cumpus has been proposed.The data were acquired by means of shalllow artificial seismic prospecting multiple coverage technique.Through computer and corresponding software,we have obtained the stratigraphic structrue and the tectonic patterns in the site by preprocessing, velocity analysis, dynamic and static correction, filtering and stack, amplitude isostasy, migration transfer method.The analysis results of the data indicate that the site has been located in a local relatively stable sedimentary environment since Quaternary, but some local movenent and inhomogeneus sedimentary phenomenon occured in the course of the depositinal procedure.The layers over 300m in the site have undergone vertical movements which have different amplitudes and frequencies for about 20 times.All the reflected interfaces are basically continuous and stable along the horizontal direction but there are some local fluctuation and disturbance.Finally, we proposed an instruction for the distribution of the biiuldings which will be constructed in this site.
