混凝土重力壩結構分析及安定條件之探討

The Stability Conditions in the Structural Analysis of Concrete Gravity Dam

摘要


本文以混凝土重力壩為對象,針對非溢流段以最佳化方法從事壩體結構分析,探討其結構分析模式之適用性及安定條件之重要性和靈敏性。安定條件包含壩體傾倒分析、壩體基礎承壓應力分析、抗剪滑分析、開裂分析及壩體應力分析,本文以實際案例加以「驗證比較,結果顯示,從事於混凝土重力壩非溢流段之結構分析時,此分析模式有其適用性,且傾倒分析為安定條件中最重要及靈敏之安定條件。

The present paper discussed the stability conditions in the structural analysis of concrete gravity dam. The stability conditions include overturning safety factor, bearing stress analysis, sliding stability analysis, cracking and allowable stress analysis. Four examples are solved and compared. It is seen that the overturning safety factor is the most important condition during the structural analysis of concrete gravity dam.
