The invention discloses a railway jointless track stress dispersing construction monitoring method, device and system. The railway jointless track stress dispersing construction monitoring system comprises a track sensor, data acquisition equipment and an intelligent terminal, wherein the track sensor is used for obtaining track information of a track at a monitoring point; the data acquisition equipment is connected with the track sensor and the intelligent terminal and used for acquiring and transmitting the track information in real time; and the intelligent terminal is used for determining real-time state information of the track according to the received track information and generating state prompting information according to the real-time state information. According to the railway jointless track stress dispersing construction monitoring method, device and system, technical problems of low working efficiency and large measuring error caused by manually measuring the track information are solved.
