摘　　要：探地雷达具有高效、灵活、便捷的特点,在越来越多的地下工程探测中得到广泛的应用。在隧道工程建设中,因不可预见的复杂地质因素,导致如突水、突泥、塌方等多种事故发生。目前,超前地质预报中的地质雷达探测技术已成为确保隧道安全掘进的关键保障。通过工程实例表明,探地雷达对隧道前方超前地质预报结果与实际揭露地质情况高度吻合,可以高效地指导现场施工,避免事故发生。Ground penetrating radar(GPR)which has the characteristics of high efficiency,flexibility and convenience has been widely used in more and more underground engineering detection.Various accidents have occurred due to unforeseen complex geological factors in the construction of the tunnel,such as water outburst and mud outburst landslide etc.At present,the geological radar detection technology in advance geological prediction has become the key guarantee to ensure the safe tunneling.The engineering example shows that the advance geological prediction results of the ground penetrating radar in front of the tunnel are highly consistent with the actual geological conditions,which can effectively guide the on-site construction and avoid accidents.
