Influences of Loading Mode and Construction Speed on Position of Phreatic Line of a Tailings Dam Weidong Lei1, a, Tielin Fu2,b, Rui Chen1,c and Wenbin Luo3,d 1Department of Civil and Environmental Engineering, Harbin Institute of Technology Shenzhen Graduate School, Shenzhen 518055, PRC 2 Liaoning Geological Engineering Investigation Construction Group, Shenyang 110031, PRC 3Jinshandian Iron Mine, Huangshi 435116, PRC alei_weidong@yahoo.com.cn, b imwwwwww@163.com, cchenrui1005@hotmail.com, dlwbjsd44@126.com Key words: Phreatic line; Construction speed; Construction mode Abstract.
Therefore, comparing with the general civil dam or natural soil slope, the tailings dam has its own engineering behaviors.
However, the engineering behaviors in seepage for tailings dam is much less studied than those for overall civil dam or slope.

The findings confirm that the proposed method improves prediction precision and provides engineers with a reliable tool to optimize concrete mix designs, thereby improving the durability and sustainability of concrete.
This research contributes to the broader field of concrete technology by advancing the application of AI-based solutions in civil engineering and related fields.
Optimizing mix proportions in material science and engineering has long been a crucial challenge, as it directly impacts the performance, durability, and cost-effectiveness of various materials and products.
By accurately predicting the water-binder ratio, engineers can exert greater control over the properties of both freshly mixed and hardened concrete, ultimately enhancing the quality and performance of construction materials.
