%X For concrete dams during operation, the moisture content of the concrete near the water level changes periodically due to the influence of water level fluctuations. When the water level drops, it will naturally lose water from saturation to dryness, and can also become saturated again due to capillary water absorption and water pressure infiltration after the water level rises. Repeated stress increases can cause damage to the concrete, and the combined effects of temperature stress and self weight may lead to cracking problems. The underwater part of the upstream surface gradually saturates under high water head, and the properties of saturated and saturated concrete may differ from those of general concrete. Experiments have been conducted to address the above issues. This dataset contains experimental research data on key parameters under the action of concrete infiltration pressure. The dataset contains an xlsx file, where the first column is the serial number, the second column is the date, the third column is the strain (μ ε), and the fourth column is the water pressure (MPa).
