摘要
基于岩滩大坝钢板计监测资料,将单位阶跃函数引入钢板计的统计模型并进行改进,构建了钢板计的阶跃函数监控模型,应用该模型与传统统计模型分析了岩滩大坝的钢板计监测资料。结果表明,该模型的精度和拟合效果均优于传统的统计模型,分离得到的各分量所占比例合理,可供类似监测项目借鉴。
According to the monitoring data of plate strain meter of Yantan Dam, this paper introduces unit step function into the statistical model of plate strain meter and establishes a step function monitoring model. Then the monitoring data of plate strain meter of Yantan Dam are analyzed using the proposed model and traditional statistical model. The results show that the precision and fitting effect of the proposed model is better than those of the traditional model and the proportion of detached components is reasonable. Thus, it provides reference for similar research.
