【摘要】 本文通过对我国二十余个大城市的活动断层探测与地震危险性评价项目实施的实践总结,讨论了探测中常见的一些关键技术问题,探讨如何根据探测深度选择不同探测技术方法;深浅组合探测;多方法综合探测应用和由粗及细提高探测精度;以及组织实施过程中的一些可能问题和解决思路。为近阶段将我国较广范围内开展城市活动断层探测与地震危险性评价工作作参考。更多还原

【Abstract】 Based on the practice of exlporations of urban active faults and assessment projects of earth quake risks in more than 20 cities in China,this paper discusses on some common key technical problems,including selection of different exploring technical methods according to different exploring depths,combination of deep and shallow explorations multimethod comprehensive exploration and its application,improvement of exploring precisions from low to high and some possible technical problems and solution of them,thus providing reference for explorations of urban active faults and assessments of earth quake risks,which will be carried out in the broad areas of China in the near future.更多还原
