Cracks often appear on mass concrete . This paper mainly introduces the temperature control measures in the construction of the 119 # pier yellow big railway 119 # pier of the bulky concrete cap of Haungda Railway Yellow River grand bridge. Through the measured data and the use of new technology, the ideal effect is obtained after form removal. The measures taken are effective, and the temperature cracks of mass concrete are controlled.%大体积混凝土往往出现裂纹，本文主要介绍黄大铁路黄河特大桥119#墩大体积混凝土承台施工过程中所采取的温度控制措施，并通过实测数据、新型工艺的使用，拆模后得到了较理想的效果，采取的一系列措施均有效，控制住了大体积混凝土的温度裂缝的产生。
