三维探地雷达在道路地下病害体探测中的应用
|
摘要
近年来,随着我国城市地下空间开发利用强度不断加大,城市浅层地质稳定性造成一定程度的影响和破坏,导致我国许多城市道路地面塌陷事故不断发生,严重影响了人民群众生命财产安全和城市运行秩序。三维探地雷达是近年来国外发展起来的一项新技术,在道路地下空洞检测、地下管线探测、工程质量检测、考古等领域应用,取得了良好的效果。利用三维探地雷达,通过多城市的工程实践,总结出一套成熟的工作方法和作业流程;并针对城市环境中的多种干扰源进行详细的分析和分类,详细描述了不同种类干扰源的地球物理特征,提出了识别和衰减的有效方法,在三维探地雷达在道路地下病害体探测应用领域进行了深入研究。
Along with urban underground space development and utilization intensity increasing recent years in the country,urban shallow geological stability has been exposed to impact and destruction to a certain extent. Thus caused many road surface subsidence accident in cities keep happening,seriously impacted people life and property safety and urban operation ordering. The 3 D ground penetrating radar is a new technology developed abroad in recent years,and applied on domains of road subsurface cavity,pipeline and project quality detection as well as engaged in archaeological studies with good effects. Through multiple urban project practices,the paper has summarized a set of mature methodology and operation process. In allusion to urban environment multiple disturbance sources carried out analysis and classification; described geophysical features of different disturbance sources in detail,put forward effective methods to recognition and attenuation. Thus the paper has carried out detailed study on 3 D ground penetrating radar in road subsurface hazard detection.
