摘　　要：为保障宁波市地铁4号线东延段的施工安全,需要对穿越区域的地层状况及可能存在的断裂带等进行精准探查。该工程采用高密度电法、浅层地震折射波法进行综合探测,查明了探测区域内的第四系分布、下伏基岩面起伏及断层分布。与单一探测方法相比,综合探测方法能够进行相互验证与综合分析,提高了解释结果的可靠性,为地铁线路的设计及施工提供了技术支撑。To ensure the construction safety of the east extension section of Ningbo Metro Line 4,it is necessary to conduct precise exploration of the stratum conditions and possible fault zones in the crossing area.The project adopts high-density electrical method and shallow seismic refraction method for comprehensive detection.The guaternary strata,underlying bedrock surface undulation and fault distribution in the detection area are identified.Compared with the single detection method,the comprehensive detection method can perform mutual verification and comprehensive analysis,the reliability of interpretation results is improved,and the technical support for the design and construction of metro lines is provided.
