A highly significant negative correlation (R 2 = 0.97) was observed between growth and yield attributes and stress-related biochemical markers, indicating that increasing metal concentration intensified oxidative injury and metabolic disruption, ultimately suppressing plant performance.
8 : During the process from pouring to consolidation stability of the pile, the expansion stress can be divided into four stages based on the evolution trend of the expansion stress of the pile expansion section over time: Rapid growth stage: During the consolidation process of the pile body, the expansion agent undergoes a hydration reaction to produce expansion stress, which continuously increases with time and reaches a peak stress of about 1600 kPa near 18 h; (ii) Loss Stage: From 18 to 25 h, the expansion stress shows a decreasing trend.
