摘　　要：为了研究“孤石”、溶洞、地下管线等城市不良地质体的高效高分辨率综合勘察技术,尝试采用纵横波综合地震方法。在标准试验场地进行了三维高密度主被动源综合地震数据采集,分析研究纵横波高分辨率处理、背景噪声成像反演地下三维速度模型、纵横波综合地质解释,探索了不良地质体的综合地震探测技术。结果表明:三维高密度纵横波联合地震勘探对试验场地的地下管线有较好的反应,在纵波剖面上表现为系列清晰的绕射波,SH波剖面上管线区域能量变弱,并且对浅层界面分层刻画得更细致,高密度纵横波综合地震勘探是探测浅层地质异常体的有效手段。In order to study the efficient and high-resolution comprehensive survey technology of urban unfavorable geological bodies such as“boulder stone”,karst caves,underground pipelines,etc.,we try to use the comprehensive seismic method with P-wave and S-wave.3D high-density active and passive source comprehensive seismic data acquisition was carried out at a standard test site,and the P-wave and S-wave high-resolution processing,background noise imaging inversion of the underground 3D velocity model,and comprehensive geological interpretation of P-wave and S-wave were analyzed to explore the comprehensive seismic detection technology of adverse geological bodies.The results show that the 3D high-density P-wave and S-wave joint seismic exploration had a good response to the underground pipelines in the test site,which was manifested as a series of clear diffraction waves on the P-wave profile.The energy of the pipeline area on the SH-wave profile became weaker,and the description of the shallow interface layering became more detailed.High-density P-wave and S-wave comprehensive seismic exploration is an effective means for detecting shallow geological anomalies.
