碾压混凝土拱坝施工仿真分析相似性研究

Similarity Research on Construction Simulation Analysis of RCC Arch Dam

通过拱坝施工仿真分析数值计算结果和实测值的反馈分析,研究施工仿真数值计算结果和实测值的相似性。结果表明:利用估测气温进行仿真计算得到的结果可以近似反映坝体温度场的分布,影响温度场和应力场分布的主要因素是工期进度安排,在仿真分析时进度安排要尽量和实际进度安排一致,这样才能保证计算结果与实际情况更相似。

Through feedback analysis and simulation analysis of calculated results and measured value,the similarity of arch dam construction simulation analysis was researched.The results show that the data obtained from numerical analysis with estimated temperature could reflect the dam temperature field approximatively.The key influencing factor to temperature field and stress field is construction arrangement.Making construction schedule consistent with the actual situation in simulating analysis,it could ensure that the results are more similar to the actual situation.
