摘　　要：工程场地隐伏断裂等地质构造的探测主要采用浅层地震勘探、电联合剖面法、电阻率测深、高密度电阻率法、地质雷达和瞬变电磁等物探方法,从介质的电性、弹性波速度及相对介电常数的变化上,获得地质构造的分布特征,通过研究物探资料上地质构造的分布关系,结合地质资料、遥感资料和同位素或热释光测年等方法,对断层的活动性做出科学的评价,对场地的合理利用,工程的安全布局都具有重要的作用。文中以长春某水泥生产线工程场地的物探勘查为例,讨论了物探方法在隐伏断裂的探测与地震活动性评价等应用问题。The geological exploration methods for geological faults include shallow seismic exploration,electrical joint section method,resistivity sounding,electrical resistivity tomography,geological radar and transient electromagnetic method. The distribution of geological structure can be detected from the velocity and relative permitivity. From the distribution of activities of faults,geological data,remote sensing data and isotope or thermoluminescence dating techniques,a scientific evaluation can be made. The above research would be important for the rational use of the site and the safety of the layout of the project. In this paper,the geophysical prospecting of a cement production line in Changchun serves as an example to discuss the exploration and activity evaluation of geophysical methods for concealed ruptures.
