“六五”期间,特别是1984年国务院决定开放十四个沿海港口城市以来的两年中,完成近40个大中城市以航磁、重力和电测深等传统物探方法为主的,比例尺为1:5万级的区域物探扫面,为基础地质、工程地质、地下水和地热资源调查提供了基础资料,取得了显著的社会经济效益。为适应近代城市建设的广泛而多方面需求,提出了新一轮城市区域物探工作内容、方法和程序的目标,其中包括地震烈度小区划,断层活动性调查,地基岩土力学分层与区划,基岩裂隙水和隐伏地热区域调查。新一轮城市区域物探工作内容、方法和程序的发展,将进一步提高城市区域物探工作水平和社会经济效益。
During the “Sixth Five-Year Plan” period, especially in the two years since the State Council decided to open 14 coastal port cities in 1984, nearly 40 large and medium-sized cities have completed the traditional geophysical methods of aeromagnetic, gravity and electrical sounding. The 1: 50000 regional geophysical scanning surface provides the basic information for basic geology, engineering geology, groundwater and geothermal resources survey, and has achieved significant social and economic benefits. In order to meet the extensive and multi-faceted needs of modern urban construction, a new round of urban geophysical exploration work content, methods and procedures, including the sub-regional seismic intensity, fault activity survey, subsoil geomechanics stratification and division, Investigation of Bedrock Fissure Water and Hidden Geothermal Area. The development of the contents, methods and procedures for geophysical exploration in the new round of urban areas will further enhance the geophysical prospect and social economic benefits in urban areas.
