| Abstract: | Jiaoxin railway recently in construction is across the Yishu fault belt which belong to famous Tanlu tectonic belt, marked by intense neotectonism and frequent seismic activity. In this case, it seems necessary to conduct a quantitative assessment and zonation of the regional crustal stability for site selecting of the Jiaoxin railway. Based on the quantitative system of classifying earth crust stability, a number of elemental parameters, including tectonic background of the region of south Shandong province, character of active faults, as well as seismological parameters, are studied considering the demand of the site selecting of Jiaoxin railway. The crustal stability is classified as stable, basically stable, comparatively stable, lack stable, and unstable. A fuzzy comprehensive analysis method is used to determine the grade of the stability. The evaluation factors and weights are taken from the results of the hierarchical analysis. By this system, the charts of the tectonic stability and crust stability partition are made. Finally, the site selecting between Zhucheng city to Xinyi city is made for Jiaoxin railway. |
