摘　　要：隧洞裂缝的修补材料有多种,针对干裂缝、渗水裂缝及衬砌表面缺陷分别采用EZ-01高渗透改性环氧树脂、OPU类聚氨脂、环氧树脂等材料进行修补。本文详细介绍了三种材料的选定及其优点、配合比和施工工艺,通过压水试验及抽查钻芯取样进行质量检验,证明EZ-01高渗透改性环氧树脂、OPU类聚氨脂在不同类型裂缝处理中均能取得较好的效果,降低了造价,节约了工期,对同类工程有借鉴意义。There are many repair materials for tunnel cracks, EZ-01 high permeahility mndified epoxy resin, OPu polyurethane, epoxy resin and other materials are respectively adopted aiming at surface defects such as dry cracks, water penetration cracks and lining surface defects. In the paper, the selection, advantages, mixing ratio and constructinn technology of three materials are introduced in detail. The quality is tested through water pressure test and sampling core boring sampling. It is proved that EZ-O1 high permeability modified epoxy resin and OPU polyurethane can achieve better effects in the treatment of different cracks, thereby lowering construction cost and saving construction duration, h has reference significance for similar projects.
