| 摘 要： | 采用“浮动网格法”对某碾压混凝土坝进行了温度仿真计算分析,得出如下结论:(1)碾压混凝土坝坝体内最高温度场受外界气温影响较大,随着外界气温的升降而升降。(2)碾压混凝土坝前期温度梯度高,降温速度快,后期降温慢,最终降至稳定温度场需要几十年时间。

| Abstract: | By using the floating mesh method,simulation analysis of a Roller Compacted Concrete Dam(RCCD) is carried out.The conclusion is:(1) the maximum temperature field of RCCD varieties in accordance with the ambient temperature.(2) The RCC dam has a higher temperature gradient in the initial stage and its temperature drops speedily in the initial stage,but slowly in the latter stage.The final stable temperature field will take tens of years to reach. |
