摘　　要：在建筑工程场地中,常常遇到人防地道、软弱层等不良地质体,对建筑物的安全造成威胁,而准确查明该类隐患,并采取相应的处理措施,是建筑工程中面临的较为普遍的问题。本文简要叙述了高密度地震映像法的基本原理和方法技术,并通过工程实例介绍了建筑场地中隐伏地道、松散夹层、湿陷性黄土等几种不良地质体的地震映像特征,并与开挖验证结果进行了对比分析,充分证明了高密度地震映像技术在建筑工程场地勘察中具有良好的应用效果。The adverse geological masses such as the air-defense tunnel and the weak layers in building sites are often encountered in tunnels,which threaten building safety.To find accurately the said hidden dangers and to adopt corresponding measures are the common problems to face in building engineering.The basic principle and technique of the high density seismic imaging method are briefly described.Through the practical project examples,the seismic imaging features of the adverse geological bodies such as the concealed tunnel,loose interlining and collapsible loess in building sites are introduced,and the comparison analysis with the excavation verification is carried out,which fully demonstrate that the high density seismic imaging technique is of the favorable application effect in the investigation of building sites.
