【摘要】 以遥感图象解译和野外地质勘查结果为依据对活动断裂分布及其活动性进行了重新核对 ,结合地震、地球物理、地壳形变等资料进行构造稳定性分区。根据铁路工程地质选线的若干要求和铁路通过区的具体特点 ,选取地质、地震、活动断裂、地质灾害和场地岩土类型为主要评价因素 ,从构造稳定性、地面稳定性、岩土体稳定性三方面进行区域地壳稳定性的评价。最后根据上述评价结果进行综合工程地质选线更多还原

【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.更多还原
