Long-term field monitoring dataset of foundation vertical deformation on medium-expansive soil

Over a monitoring period of 974 days, two critical parameters were recorded to evaluate the performance of the four foundations. The first parameter, vertical deformations, was measured using dial gauges. To ensure precision and accuracy, these measurements were validated with advanced instruments, including the line laser GLL 3-80 Professional and the LEICA DNA 10 digital levels. The second parameter involved the weekly cumulative rainfall, which was obtained from the General Directorate of Agriculture in Erbil, operating under the Ministry of Agriculture and Water Resources, Kurdistan Regional Government (KRG). This rainfall data was crucial for assessing the impact of environmental factors on the foundations over the study period. The table summarizes the data collected over time for the deformations in the foundation and rainfall, clearly categorized into three data sets: Recorded Data - showing measured vertical deformation in millimeters for four foundation footings, Footing_1 to Footing_4, for particular dates. It shows that all the observed vertical deformations varied upward (+) over the period taken into consideration. The Vertical Deformation section shows incremental changes in the deformation with respect to the baseline date of 28 November 2021, and the footings show some variation. The data on the Weekly Cumulative Rainfall is in millimeters, and it can be seen that the fluctuations fall with periods of heavy precipitation, while at those instants in time the fluctuations of the footings deformation are quite great. These data combined show the ongoing interaction between environmental factors with the underlying deformation behavior of the foundations over time.本研究在为期974天的监测周期内，记录了两项关键参数以评估四座基础的工作性能。第一项参数为垂直变形，通过百分表（dial gauge）采集；为保障测量精度与准确性，研究采用线激光水平仪GLL 3-80 Professional及徕卡DNA 10数字水准仪等高端仪器对测量结果进行了校核验证。第二项参数为周累积降雨量，数据来源于库尔德斯坦地区政府（KRG）农业与水利资源部下辖的埃尔比勒农业总局。该降雨数据对于评估研究周期内环境因素对基础的影响至关重要。本表格汇总了随时间采集的基础变形与降雨数据，并明确划分为三类数据集：实测数据（Recorded Data）——记录了特定日期下四座基础承台Footing_1至Footing_4的垂直变形实测值，单位为毫米。数据显示，本次监测周期内所有实测垂直变形均呈现向上（+）的变化趋势。垂直变形部分以2021年11月28日为基准日期，展示了变形的增量变化情况，各承台间存在一定差异。周累积降雨量数据单位为毫米，可见当出现强降水时段时，降雨量波动显著，与此同时各承台的变形波动也较为剧烈。综合上述数据可知，在整个监测周期内，环境因素与基础的潜在变形行为之间存在持续的相互作用。
