摘　　要：按渗漏水量和水源补给情况对公路隧道渗漏水进行了分类,并从设计理念、施工质量控制和养护水平3个层面研究了公路隧道渗漏水病害的成因;公路隧道渗漏水的治理措施主要包括封堵和引排,针对目前传统排水管易堵塞的缺点,首先介绍了新型排水材料毛细透排水管的基本构造及安装方式,然后通过排水试验研究表明,毛细透排水管的排水能力随着渗水压力的增大而增大,排水能力能够满足公路隧道渗漏水处排水需要,且抗淤堵试验的结果显示了通过毛细透排水管排出的渗水较为清澈,无泥沙淤堵,排水量稳定,具有良好的抗淤堵能力。最后,工程实例的跟踪监测结果验证了毛细透排水管治理公路隧道渗漏水的适用性和有效性。Highway tunnel leakage conditions are classified based on leakage amount and water supply status. The highway tunnel leakage causes are studied at the levels of design concept, construction quality control and maintenance. Highway tunnel leakage treatment measures include plugging and draining. In allusion to the shortcomings of susceptible plugging of traditional drainage pipe, the structure and installation of the siphon drainage pipe made of a new drainage material are introduced at first. The drainage experiment result shows that the drainage capacity of the siphon drainage pipe is enhanced with the increasing of osmotic pressure, the drainage capacity of the siphon drainage pipe can meet the drainage needs for highway tunnel leakage treatment. The anti-clogging experiment result shows that water from siphon drainage pipe is clear, the siphon drainage pipe has not been blocked up by mud, the drainage amount is also stable, and the siphon drainage pipe can provide a good anti-clogging capability. At last, the adaptability and effectiveness of siphon drainage pipe for treating highway tunnel leakage are illustrated by continuous monitoring results of a tunnel engineering case.
