| 以往城市地下空间探测主要采用钻探结合以电阻率方法为主的传统电法勘探，但钻探施工成本高且破坏性较大，传统物探精度相对较低。为建立基于物探探测精度和经济性的综合方法组合模式，本文在综合分析前人相关研究基础上，选择了传统电法中的高密度电法、浅层地震中的面波法和地震映像法、国内新兴的SSP地震散射波法，检验其在铁路顶管、疏松体、地下空洞等城市浅层地下目标体探测中的应用效果。通过城区地下不同地质结构地球物理综合方法应用探索，取得主要结论与成果有：（1）总结了不同地质条件下各方法的优点及局限性；（2）建立了不同工况下基于经济性和探测精度的可参考物探组合模式。研究成果一方面有助于提升城市浅部地下空间探测精度，具备可转化应用的较大经济价值；另一方面作为相对前沿和系统的方法有效性研究，对推动城市地球物理发展具有重要意义。 |

| Traditional underground space exploration in urban was mainly realized by drilling and traditional electrical exploration methods， such as resistivity method. However， drilling method is expensive and destructive， and the accuracies of traditional geophysical explorations are relatively low. In order to establish an integrated geophysical prospecting method with the high accuracy and low cost， in this paper， combined with previous research， the high-density electrical method in the traditional electrical methods， the surface wave method and seismic image method in shallow seismic methods and an emerging domestic method called SSP seismic scattering wave method are used to examine their application effects on the detection of shallow urban underground targets， such as railroad pipe jacking， loose bodies and underground cavities. By exploring the application of the integrated geophysical method in different underground geological structures in urban areas， the main results we obtained are as follow： （1）the advantages and limitations of each methods under different geological conditions are summarized； （2）a reference valuable geophysical exploration combination model with high detection accuracy and low cost under different working conditions is established. The result of this research could help to improve the accuracy of detection of shallow urban， underground space， and show economic value of application. Besides， as a relatively cutting-edge and systematic research on the effectiveness of the method， this research is beneficial of the development of urban geophysics. |
