According to the monitoring project of the arch bridge of Ma Zhang Dam, with the mass concrete of its I-shaped bearing platform as the analysis object, the temperature sensor is set up in the construction process, and the temperature field changes in the bearing platform are monitored in real time, and the internal change law of the mass concrete temperature field is measured. The results show that the highest temperature of 1# with 2.5m high I-shaped platform appears at 27h after full warehouse, which is 70.4°C; the highest temperature of 2# appeared at 17h after full storage, which was 65.5 °C, exceeding the limit of 5°C. Therefore, the cooling cycle water pipe is set up in the construction process, the cooling measures are taken in time, and the cracks are not appeared in the platform, which provides a certain basis for the construction of the mass concrete in the future.
