该文采用有限元方法按照实际浇筑顺序对沉管管体制作的全过程作了数值仿真,分别分析了夏季和冬季施工条件下管体混凝土温度场分布及其变化规律,以及采用冷却骨料混凝土浇筑侧墙对侧墙温度场的影响.结果表明,冷却骨料混凝土可有效地降低侧墙内部温度和温度变化.“,”The Finite Element Method is adopted in this paper to simulate the whole constructing course of immersed tunnel unit according to the actual casting procedure. The distribution of tempera ture and the rule of temperature variation are analyzed under the construction situation of winter and summer. The effect of cooling material which leads to low-temperature concrete on the thermal field of the side-wall is also analyzed. The result shows that the cooling concrete can lower the temperature and the temperature variation of the side-wall effectively.
