Data for: Performance of data-based models for early detection of damage in concrete dams

Crest displacement [mm] data from simulations of the seasonal displacements of a Buttress dam for 18 years. The data is used for evaluation of the accuracy of damage detection. The data consists of one column with crest displacement from the undamaged dam (UD) and nine rows of crest displacement from the dam with various types of damage. Three locations of damage in the dam and three scenarios were used. The first two locations were to introduce damage in either the whole front plate (FP) or the whole buttress (Bu). The third location was to introduce damage only in cracks corresponding to the crack pattern (Cr) observed at the dam. The three damage time scenarios were used: -Continuous decrease (C) -Instantaneous decrease (I) -Seasonal decrease (S) The data also includes the water temperature, the air temperature outside and air temperature in the dam enclosed area between the front plate and the insulating wall.本数据集包含某支墩坝（Buttress Dam）18年季节性位移仿真所得的坝顶位移（单位：mm）数据，该数据用于损伤检测精度的评估。 数据表格包含一列未损伤坝（Undamaged Dam，UD）的坝顶位移数据，以及九行对应各类损伤坝体的坝顶位移数据。本次实验设置了三种坝体损伤位置与三种损伤演化场景。 前两种损伤位置分别为：对整体前盖板（Front Plate，FP）施加损伤，或对整体支墩（Buttress，Bu）施加损伤；第三种损伤位置则仅针对坝体实测的裂纹模式（Crack Pattern，Cr）施加裂纹损伤。 本次采用的三种损伤时间演化场景如下： - 持续衰减（Continuous Decrease，C） - 瞬时衰减（Instantaneous Decrease，I） - 季节性衰减（Seasonal Decrease，S） 本数据集同时涵盖水体温度、外部大气温度，以及前盖板与隔热墙之间坝体封闭区域内的大气温度数据。

背景概述

该数据集包含一个扶壁坝18年模拟的坝顶位移数据，用于评估基于数据的模型在混凝土坝损伤早期检测中的性能。数据涵盖未损伤状态和九种不同损伤类型（涉及三个损伤位置和三种时间场景），并额外提供水温、外部气温和坝内气温等环境变量，以支持损伤检测的准确性分析。
