城市道路地下空洞及缺陷是威胁城市交通安全的重要风险源,一直是城市交通工程安全难以攻克的课题。随着城市道路管理的地理信息化,结合有效的检测手段和方法,及时掌握道路地下空洞和土层的密实、松散信息,对于城市道路安全具有非常重要的意义。目前,探地雷达技术在我国广泛应用于道路的无损探测中,而且取得了较好的检测效果。本文论述了一个关于探地雷达技术在长安街道路探测中的典型应用范例。
The underground tunnels and defects in urban roads are the important risk sources that threaten urban traffic safety and have always been the topics that are difficult to overcome in urban traffic engineering. With the geographic informationization of urban road management, combined with effective detection methods and methods, it is very important for urban road safety to grasp the dense and loose information of the underground tunnels and soil layers in time. At present, GPR technology is widely used in nondestructive detection of roads in our country, and has achieved good detection results. This article discusses a typical application of GPR technology in Chang’an Avenue detection.
