The utility model discloses a tunnel settlement joint water seepage monitoring and alarming system, belongs to the technical field of tunnel structure monitoring, and solves the problem of how to judge tunnel structure change according to settlement joint water seepage conditions. A seepage collecting groove is formed around the inner wall of the tunnel along the settlement joint, a seepage collecting pool is arranged at the lower end of the seepage collecting groove, and a water level detector is arranged in the seepage collecting pool and connected with a tunnel monitoring device. Seepage water of the settlement joint is collected through the seepage water collecting groove and collected into the seepage water collecting pool, the water level change in the seepage water collecting pool is monitored in real time through the water level detector, and when the seepage water in the seepage water collecting pool is collected to a certain degree and the liquid level detector monitors the warning water level, a si
