摘要
通过建立新安江大坝3#坝段坝基总扬压力数值模型,分析了3#坝段坝基总扬压力的变化趋势和主要影响因素,并用概率法计算了坝基总扬压力的可能最大值。分析结果表明:3#坝段扬压力主要受上游水位影响且时效尚未完全稳定。
The observation data show 3 # Section uplift pressure of Xinanjiang Dam is abnormal. This paper presents an analytical method of dam uplift pressure by establishing the whole section uplift pressure model. The results show 3 # Section uplift pressure of Xinanjiang dam was influenced mostly by water level, and the time effect of 3 # Section uplift pressure have not been stabilized. Then, the utmost uplift pressure of dam was studied by probability.
