| 本文以兰州城区以往道路塌陷区域为研究对象，针对城市地面塌陷灾害问题开展多种地球物理方法的组合探测试验。通过对比室内与室外试验效果，系统分析探地雷达、微动勘探法、地震映像法及等值反磁通瞬变电磁法等现有精细物探方法的适用性与局限性。研究结果显示，多种勘探技术的联合应用能够实现相互验证，进而提升勘探成果的精确度，并全方位地揭示地下构造特征；经过多次数据迭代与精细化优化，构建针对性显著、数据互补性强、能够有效压制噪声干扰的综合地球物理勘探方法体系，该体系不仅充分考量了各类地质条件下的勘探需求，还兼顾了经济效益，为道路病害检测及浅表地质结构调查提供了坚实的科学依据与技术保障。研究成果不仅为兰州城区道路塌陷的探测问题提供了有效的解决方案，同时也为在相似地质条件下的城市地质病害体调查工作提供了重要的参考范例与借鉴价值。 |
| 英文摘要: |
| Ｔhis article takes the past road collapse areas in the urban area of Lanzhou as the research object, and conducts a combination detection experiment of multiple geophysical methods to address the problem of urban ground collapse disasters. By comparing the indoor and outdoor test results, the applicability and limitations of existing fine geophysical methods such as ground penetrating radar, micro motion exploration method, seismic imaging method, and equivalent inverse magnetic flux transient electromagnetic method are systematically analyzed. The research results show that the joint application of multiple exploration techniques can achieve mutual verification, thereby improving the accuracy of exploration results and revealing the characteristics of underground structures in all aspects; After multiple iterations and refined optimization of data, a comprehensive geophysical exploration method system with significant targeting, strong data complementarity, and effective suppression of noise interference has been constructed. This system not only fully considers the exploration needs under various geological conditions, but also takes into account economic benefits, providing solid scientific basis and technical support for road disease detection and shallow geological structure investigation. The research results not only provide effective solutions for the detection of road collapses in the urban area of Lanzhou, but also provide important reference examples and reference value for the investigation of urban geological hazards under similar geological conditions. |
