Abstract：Research purposes ： Active faults and ground fissures are developed in Beijing area of a pBsenger dedicated line，which bring about great geologic hazard for the design construction and operation safety of high - speed railway. Based on predecessors" research，this paper used comprehensive survey technology to probe the spatial distribution and the geological characteristics of the active faults and ground fissures along the railway，such as geophysical prosj^ecting， borehole surveying (trenching)，and the sample test and so on，and analyzed the technical feasibility and effectiveness. According to the design characteristic of railway engineering， evaluated and researched on the fault activity， ground fissure disasters and regional seismic safety， to provide the necessary survey data and the suggestion for the railway geological line selection，design，construction and prevention after construction. Research conclusions ：( 1) Engineering geophysical prosj^ecting as the main integrated survey technology in active fault exploration and evaluation is effective and reliable，able to reveal the geological characteristics and spatial distribution of the active faults and the ground fissures，and meet the needs of railway survey and design of pasenger dedicated line. (2) This paper proposed various fracture activity，ground fissure disaster and seismic safety evaluation of Beijing nortii activity fracture zone， the evaluation results is the basis of the furtiier design of pasenger dedicated line and the prevention and control after construction. (3) The research achievements have guiding significance for the similar railway survey and design, and have strong generalization value in the field of highway$ water conservancy and hydropower，and other civil.
