地下空间作为城市智能管理与运营的实体介质，具备缓解城市资源紧张以及实现低碳智慧城市的重要功能。如何实现城市强干扰环境地下结构“透明化”是科学、合理、安全开发利用城市地下空间的关键。针对城市地质地物复杂多变以及强干扰环境，多参数融合互补模式有助于城市地下空间更小尺度的精细结构演化特征调查，并且为未来地下空间数字化建模提供多源信息。本研究在贵州安顺市紫云自治县融合地质雷达、高密度电法及被动源面波等参数来反演解释其浅层地下空间以及异常体结构特征。其中，利用地质雷达探明场区表层土体密实度及空洞情况，弥补浅表层探测盲区问题；利用被动源面波获取地下更深横波速度并解释溶洞分布现象；高密度电法电阻率分布同样对地下结构与岩溶发育具有较好的敏感度，与被动源面波成果相互佐证。综合三种参数解释结果，并将其与现场钻孔资料进行对比验证，结果表明两者具有较高的一致性。由此可见，结合多参数融合成像能够克服异常多解性，更准确地揭示地下空间结构特征，为灾害监测以及后期透明城市地下空间构建提供多源参数。
Abstract：Underground space, as a physical medium for intelligent management and operation of cities, has important functions in alleviating urban resource shortages and achieving low-carbon smart cities. How to achieve the “transparency” of underground structures in urban strong interference environments is the key to scientifically, reasonably, and safely developing and utilizing urban underground spaces. The multi parameter fusion complementary model is helpful for investigating the fine structural evolution characteristics of urban underground spaces at a smaller scale, and providing multi-source information for future digital modeling of underground spaces, in response to the complex and varied geological features and strong interference environments in cities. We integrated geological radar, high-density electrical methods, and passive source surface waves in Ziyun Autonomous County, Anshun City, Guizhou Province to invert and interpret the shallow underground space and structural characteristics of anomalous bodies. Geological radar is used to determine the density and voids of the surface soil in the field area, and to compensate for the blind spots in shallow surface detection; Passive source surface wave acquisition of underground deeper transverse wave velocity and interpretation of karst cave distribution phenomena; The high-density electrical resistivity distribution also has good sensitivity to underground structures and karst development, which is mutually supported by the results of passive source surface waves. Based on the interpretation of three parameters and their comparison with on-site drilling data, the results show a high degree of consistency between the two. From this, it can be seen that combining multi parameter fusion imaging can overcome abnormal ambiguity, more accurately reveal the structural characteristics of underground space, and provide multi-source parameters for disaster monitoring and later transparent urban underground space construction.
