摘要
随着隧道建设实践探索的不断深入和对防排水规律认识的加深,我国隧道防排水技术逐步发展.通过梳理隧道防排水技术及材料发展历程,可大致将其分为建国前无防排水设计阶段、20世纪50年代压浆防水阶段、20世纪60~70年代以排为主阶段和20世纪80年代至今"防、排、截、堵结合"阶段共4个阶段,并对不同阶段的防排水设计重心以及防排水技术措施的产生过程进行总结.随后,阐述目前隧道防排水系统组成的现状,并对防(排)水板、排水盲管和衬砌接缝防水止水带进行重点介绍.最后,从设计、材料、施工3个方面对未来几年隧道防排水的发展方向和研究重点进行展望.
Abstract
As exploration of tunnel construction practices deepens and understanding of waterproofing and drainage laws improves,tunnel waterproofing and drainage technologies in China have gradually developed.By reviewing the evolution of tunnel waterproofing and drainage technologies and materials,it can be roughly divided into four stages:the stage with no drainage design,the grouting waterproofing stage of the 1950s,the drainage-focused stage of the 1960s to 1970s,and the"waterproofing,drainage,interception,and plugging"stage from the 1980s to the present.This summary also covers the focus of waterproofing and drainage design in different stages and the development of waterproofing and drainage technologies and measures.Subsequently,the current state of the tunnel waterproofing and drainage system is described,with a focus on the introduction of drainage plates,blind drains,and waterproof stoppers for lining joints.Finally,from the perspectives of design,materials,and construction,the paper looks ahead to the future directions and research focuses of tunnel waterproofing and drainage in the coming years.
