Abstract：The problem of anti-crack and anti-seepage of concrete in open-cut tunnel engineering has been a difficult problem for engineers for a long time. This paper summarizes the current situation of leakage caused by anti-crack and anti-seepage of tunnels，the engineering hazards thus arising，and the significance of carrying out research on anti-crack and anti-seepage，and analyzes the common problems and causes of concrete self-waterproofing，external waterproofing，joint waterproofing，and leakage seepage water treatment. On this basis，the lifting technical direction and measures of anti-crack and anti-seepage of concrete in open-cut tunnel engineering are put forward，in order to provide new technical ideas for anti-crack and anti-seepage of such engineering.
Key words：open-cut tunnel engineering，anti-crack and anti-seepage，self-waterproofing，external waterproofing
