| Abstract: | According to the complicated geology and climatic conditions during the construction period of Zhuzhou Ship Lock, the measures for avoiding crevices, such as reducing heat of hydration concrete, controlling concrete temperature when it enters the barn, and casting layer by layer, etc. are taken. This paper analyzes the temperature control effect, and draws some beneficial conclusions by the way of finite element to simulate the transient temperature pattern of the lock head floor. |
