Field Study of Foundation Performance on Medium-Expansive Soils

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.

在为期974天的监测期间，针对四个基础性能的评估记录了两个关键参数。首先，垂直变形参数通过使用游标卡尺进行测量。为确保测量的精确性与准确性，这些数据通过包括线激光器 GLL 3-80 专业版和 LEICA DNA 10 数显水平仪在内的先进仪器进行了验证。第二个参数涉及每周累积降水量，该数据由库尔德自治区政府（KRG）农业与水资源部下属的农业总局提供。这些降水数据对于评估研究期间环境因素对基础的影响至关重要。
