地质雷达技术在城市地面塌陷隐患调查中的应用

Application of Ground Penetrating Radar to Investigation of Hidden Danger of Urban Ground Collapse

随着城市化建设的发展,城市道路建设及地下空间的利用也快速推进,由于一些自然的、人为的及客观的原因,导致了地下隐患的产生、发展并最终引发道路地面塌陷灾害的发生。因此,查明城市道路地下隐患的位置并采取工程措施将地面塌陷灾害消除在萌芽之初,是政府的责任更是勘查人员的责任。在对地面塌陷成因分析认识的基础上,根据可能适用于城市道路地下隐患的勘察技术的特点及工作环境条件,并结合实例分析,就地面塌陷灾害隐患的各种地球物理探测方法技术及探测效果进行探讨、比较和评价,从而给出用于城市道路地面塌陷隐患的实用、有效的调查方法技术。

With the development of urbanization,the construction of urban roads and the utilization of underground space have also been rapidly advanced.Meanwhile,due to some natural,man-made or objective reasons,the occurrence and the development of underground hidden dangers have eventually lead to the road ground collapse disasters.Given the high frequency of domestic ground collapse events,it is urgent not only for the government but also for the geological surveyors to identify the location of urban road underground hidden dangers and take engineering measures to eliminate the ground collapse risks at the very beginning.Based on the analysis of the causes of ground collapse as well as the characteristics of survey technologies and working conditions,this paper discussed,compared and evaluated various geophysical detection methods and their effects on detecting the hidden dangers of ground collapse with examples.Through the comparison and evaluation,this paper aims to propose a practical and effective investigation method for the hidden dangers of urban road collapse.
