高密度电法3D解译于道路塌陷的应用研究

研究高密度电法三维解译方法,为城市道路塌陷应急抢险及治理方案提供科学依据,具有一定社会经济效益。首先阐述了高密度电法探测地下空洞的理论基础,然后通过某城市道路因地铁开挖而导致路面塌陷的案例,应用高密度电法三维解译方法,准确探测出道路塌陷区域地下空洞的分布位置及范围。探测结果表明,空洞分布范围覆盖了路中间绿化带地面塌陷区域,空洞的中心深度距路面约2.3m。根据探测结果积极有效地治理塌陷道路,排除了较大的安全隐患。

3DInterpretation of Applying High-densityElectrical Method in Road Collapse

The 3Dinterpretation of high-density electrical method can provide scientific basis for urban road collapseemergency rescue and treatment scheme,which has certain social and economic benefits.Firstly,the theoretical basisof the high-density electrical method to detect the underground cavity is elaborated,then the 3Dinterpretation of high-density electrical method is applied to an example of the road collapse in a city that caused by the excavation of subwayproject.Application of the method can accurately detect thedistribution scope and location of the underground cavity.The detection results indicate that the range of the underground cavity covers the subsidence of green belt in themiddle of the road,andthe central depth of the cavity is about 2.3mto the pavement.The road collapse is controlledeffectively and actively according to the results of the detecting,and the potential safety hazard is eliminated.
