Abstract The long-term durability of the tunnel lining following crack grouting serves as a major guiding principle in the choice and enhancement of crack treatment techniques. According to the field investigation，a 420-day crack grouting and secondary corrosion test of concrete with non-through cracks was carried out，along with uniaxial compression and acoustic emission tests，in order to examine the impact of non-through crack grouting on the compressive characteristics of tunnel lining concrete under the secondary sulfate corrosion of free surface evaporation. The test findings demonstrate that the compressive failure features of concrete corroded by sulfate change from diagonal conical failure to full spalling on one side of the attacked surface. In addition，non-through deep cracks accelerate the strength loss of concrete in a sulfate environment. During the uniaxial compression，the acoustic emission stages I–IV show good agreement with the stress-strain curve in the following stages：the compression stage，elastic stage，yield stage，and post peak-stage. Furthermore，with increasing the corrosion time，the compression yield point of the specimen advances，the proportion of stage Ⅱ decreases，and the proportion of stage Ⅲ increases. Non-through crack grouting increases the concrete?s immediate strength and decreases its strength loss during secondary corrosion. However，non-through crack grouting had no effect on the concrete?s damage or acoustic emission characteristics during the compression process，and the grouting effect diminishes as the grouting time increases.
