| Abstract: | According to the construction schedule of Zhuzhou Navigation Power Junction, the shiplock concrete construction engineering was arranged to implement in July and August, when the temperature is higher. So, the concrete temperature control is an important problem. This paper simulates the transient temperature field during construction period of ship lock head floor concrete, and analyzes the effect of "controlling concrete pouring temperature and setting up construction joints". Some beneficial conclusions are drawn and the main achievements have been adopted in design and construction. |
