摘　　要：以杭州某公路兼顾城市道路地下明挖隧道工程为依托,从防水理念、混凝土自防水、变形缝防水及隧道内渗漏水引排等角度分析了城市公路明挖隧道防排水体系的设计要点,包括确立以钢筋混凝土结构自防水为根本,以接缝防水为重点,在结构迎水面设置全包柔性防水层等多道防线的综合防水体系,同时采取在隧道内变形缝等易渗漏的接缝处设置接水盒等集中引排措施。Based on the underground open cut tunnel project of a certain highway in Hangzhou,this paper analyzes the design points of the waterproofing and drainage system for urban highway open cut tunnels from the perspectives of waterproofing concept,concrete self-waterproofing,deformation joint waterproofing and water drainage for leakage inside tunnel etc.The design points include establishing comprehensive waterproofing system which takes reinforced concrete structural self-waterproofing as the fundamental,joint waterproofing as the focus,anda fully wrapped flexible waterproofing layer is set for the water facing surface of the structure.Meanwhile,centralized drainage measures such as setting water collecting boxes at deformation joints and other easily leaking joints in the tunnel are also taken.
