李家峡拱坝二级安全监控指标研究

Research on secondary safety monitoring indexes of Lijiaxia arch dam

通过建立三维非线性有限元模型,用结构计算分析方法拟定李家峡拱坝的变形二级安全监控指标,可评估和预测抵御可能发生荷载的能力,保证坝体的安全运行。本文所用的方法也为其他安全监控指标的拟定提供有效的思路。

Three-dimensional nonlinear finite element model of Lijiaxia arch dam is established, and the secondary safety monitoring indexes for displacement of Lijiaxia arch dam is determined. By analyzing the indexes, safety operation of the dam can be ensured. This paper also provides a new way to determine other kinds of safety monitoring indexes.
