成都市城市道路塌陷成因及快速探测方法

Causes and rapid detection methods of urban road collapse in Chengdu City

城市道路塌陷严重危害城市公共安全,对城市道路塌陷隐患进行快速、准确、绿色的探测,有助于减少城市地下病害发育,提升城市安全运营能力。通过调查分析,成都市城市道路塌陷的主要成因包括地质结构复杂、地下水丰富、人类工程活动频繁等。采用车载三维探地雷达对城市道路进行快速探测,建立了以探测、解译、验证、评估、成果及信息化管理为系统的探测体系。实践表明,车载三维探地雷达是快速探测城市道路塌陷隐患的有效方法。

The urban public safety is seriously endangered by urban road collapse.The rapid,accurate and green detection of hidden dangers of urban road collapse will help reduce the development of urban underground diseases and improve the ability of urban safe operation.The main causes of urban road collapse in Chengdu City include complex geological structure,abundant groundwater and frequent humanistic engineering activities through investigation and analysis.The vehicle mounted three-dimensional geological radar is used to conduct a quick detection on urban roads,and a detection system is established based on detection,interpretation,verification,evaluation,results and information management.The results show that vehicle mounted 3D geological radar is an effective method for rapid detection of hidden dangers of urban road collapse.
