摘　　要：公路隧道水害严重影响隧道的运行安全,调查并确定水害发生的原因对隧道水害的治理起到至关重要的作用,而由于运营隧道交通组织复杂及现场调查条件的限制,一般采用水文地质调查结合地球物理探测技术调查隧道水害的成因。以京珠粤北高速公路洋碰隧道发生水害现象为工程实例,提出了在不中断交通情况下的精细水文地质调查加地震映像法这一综合地质调查技术,查清了洋碰隧道的不良地质及衬砌病害整体情况,并提出了水害的初步处治意见。Highway tunnel water damage seriously affect the safety of tunnel operation,investigate and determine the cause of the water damage plays an significant role in tunnel water disasters treatment.However,due to the complexity of traffic organization and limitation of field investigation in an operational tunnel,hydrogeology survey combined with geophysical detection technology usually adopted to investigate the cause of tunnel water disasters.Based on the water damage in Yangpeng tunnel of Beijing-Zhuhai expressway in northern Guangdong,this paper proposed a comprehensive geological survey technology under the condition of uninterrupted traffic,which combining the seismic imaging method and fine hydrogeology survey.This paper also found out the overall condition of Yangpeng tunnel’s poor geology and lining diseases,put forward the preliminary opinions on the treatment of water damage.
