色气湾台伸缩仪受水库蓄水载荷变化影响分析

Analysis of the Influence of Reservoir Water Storage Load Variation on the Extensometer at Seqiwan Bay

摘要: 本文通过分析包头地区强降雨对包头市色气湾台伸缩仪观测资料的影响特征，结合水库蓄水加卸载作用建立数值模型进行定量分析。结果表明，荷载变化量产生的影响量级与伸缩仪的限定指标接近，附近昆都仑水库的巨量蓄水对包头市色气湾台伸缩仪形变观测产生持续影响。

Abstract: In this paper, the influence characteristics of heavy rainfall in Baotou area on the observation data of the extensometer at Saqiwang platform in Botou City are analyzed, and a numerical model is established for quantitative analysis in combination with the water storage and unloading effect of the reservoir. The results show that the magnitude of influence generated by the load change is close to the limit index of the extensometer, and the massive water storage of the nearby Kundulun reservoir has a sustained effect on deformation observation of the extensometer at Saqiwang platform in Baotou City.
