摘　　要：通过对特高拱坝无应力计原型观测资料的分析,介绍了无应力计出现有应力状态的变化过程,分析了可能产生这种异常现象的原因。并分析计算了无应力计筒内混凝土的垂直应力,初步探讨了高应力对无应力计测值的影响。Based on the monitoring data of non-stress meters in an ultra-high arch dam,the changing process of stress by means of the non-stress meters is discussed.The possible causes for this anomaly are analyzed.The stress of the concrete in the barrel of the non-stress meters is calculated.The influence of high stress on the measured values of the non-stress meters is preliminarily discussed.
