摘要
为了大坝的安全施工,利用大型有限元软件ANSYS对位于新疆某水电站碾压混凝土重力坝段进行了有限元仿真计算,获得了该坝段混凝土结构温度场和温度应力场的分布及其随时间的变化规律。结果表明:严寒地区坝体越冬层面对大坝建成后裂缝产生有较大影响,在施工期和运行期应采取保温措施。
For the safe construction of dam, using the large software of ANSYS, the simulation analysis was carried out for the RCC gravity dam of a hydro-electric power in Xinjiang. The distribution and changing rule with time of the temperature field and thermal stress field of concrete structures of the dam have been obtained. The results have shown that the overwintering bedding surface of the dam in extreme cold region has a great effect on dam crack, so in the construction and operation period the heat preservation measures must be taken.
