摘　　要：面对浙西地区复杂的地质坏境,采用单一物探方法难以满足拟建隧道地质勘察的探测要求,并存在很大的数据解释局限性。这里就浙西地区拟建隧道勘察为背景实例,通过实例数据处理和成果验证对比,案例论证了综合物探技术的优势及应用的必要性。初步分析,多种物探方法的有机结合和相互验证,更能准确地查明隧道穿越区不良地质情况、各岩层风化层深度、异常形态及分布情况等地质信息,极大地提高了物探资料的解译精度和可靠性。For the complex geological environment in western Zhejiang,it is difficult to meet the exploration requirements of geological prospecting for proposed tunnels by single geophysical prospecting method,leading to great limitations in data interpretation.Taking the prospecting of the proposed tunnels in western Zhejiang as a background example,this paper demonstrates the advantages of integrated geophysical prospecting technology and the necessity of its application through data processing and results verification and comparison.Preliminary analyzing show that the organic combination and mutual validation of various geophysical methods can more accurately identify the geological information,including bad geological conditions,depth of weathered strata,abnormal shape and distribution in the tunnel crossing area,which greatly improves the interpretation accuracy and reliability of geophysical data.
