城市浅层地下空间探测技术对比与分析

Comparison and Analysis of Urban Shallow Underground Space Detection Technology

为优选适合于城市浅层地下空间探测的有效技术手段,以某地人防工事为主要研究对象,采用新型地质雷达、微动探测技术和高密度电法等多种探测技术开展对比试验。结果表明,新型地质雷达和微动探测技术具有抗干扰能力强、分辨率高、场地环境要求低的特征,两种方法综合利用对地下空间探测具有较好的效果。高密度电法对场地条件要求较高,在适宜的场地条件下也具有很好的分辨能力。

As an indispensable component of urban infrastructure,the urban shallow underground space is inextricably linked with people’s lives.Therefore,it is important for the accurate detection and evaluation of shallow underground space in urban areas.A certain air defense fortification as the main research object,and a variety of detection technologies are adopted such as the new geological radar,micro motion detection technology and the high-density electrical method to carry out comparative tests.The optimized the effective technical means suitable for the detection of urban shallow underground space is found out which provides technical support for the detection of underground structures and hidden dangers.Results show that the new type of geological radar and micro detection technology have a strong anti-interference ability,high resolution,low space environment.What’s more,the characteristics of the comprehensive utilization of two methods for the detection of underground space show a good effect and prove to be a high density resistivity method for site conditions though the demand is higher.
