综合物探技术在城市道路塌陷灾害治理中的应用

Application of Comprehensive Geophysical Exploration Technology in Emergency Treatment of Urban Road Collapse

近年来,城市道路塌陷灾害频发,通过物探手段能快速探明塌陷点及周边重点区域范围内地下隐伏病害的位置、深度及规模,为塌陷灾害治理提供基础资料与技术支持。对地下病害进行针对性的治理,不仅能提高塌陷灾害治理效率、节约治理成本,更能有效避免塌陷灾害复发。文章通过对多种物探方法特点进行分析,结合城市道路现场环境特点,提出了探地雷达法与地震散射波法相结合的综合物探技术对城市道路地下病害进行探测,并在城市道路塌陷灾害治理过程中取得了良好的应用效果。

In recent years,urban road collapse disasters occur frequently.The location,depth and scale of the underground hidden diseases can be quickly detected by means of geophysical prospecting,whichProviding basic data and technical support for collapse disaster management.The targeted treatment of underground diseases can not only improve the treatment efficiency of collapse disaster,save the cost of treatment,but also effectively avoid the recurrence of collapse disaster.Based on the analysis of the characteristics of various geophysical methods,combined with the characteristics of the site environment of urban roads,this paper puts forward a comprehensive geophysical technology which combines the GPR method and the seismic scattering wave method to detect the underground diseases of urban roads.It has achieved good application effect in the process of urban road collapse disaster treatment.
