Temperature effect modeling in structural health monitoring of concrete dams using kernel extreme learning machines

Kang, Fei, Liu, Xi, Li, Junjie·2020·Structural Health Monitoring

Abstract

Statistical models have been used for dam health monitoring for many years and have achieved some successful applications. In the statistical model, dam structural response is related to external environmental factors such as reservoir water level, temperature, and irreversible time deformation. For concrete dams, the structural response is affected greatly by the ambient temperature. Therefore, in order to establish a more reliable dam health monitoring model, the temperature effect and modeling method should be further studied. This article presents a dam health monitoring model using measured air temperature for temperature effect simulation based on kernel extreme learning machines. The temperature effect is simulated by long-term air temperature data, and the nonlinear relationship is modeled by kernel extreme learning machines, which is an intelligent machine learning technique with high learning speed and good generalization performance. The proposed dam health monitoring model is verified on a real concrete gravity dam with efficient safety monitoring data. Results show that the proposed approach with a variable set recommended for concrete dam behavior prediction is feasible.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
