2025年7月25日，团队负责人王苏然与团队成员李溢共同前往德国弗莱贝格工业大学，拜访岩石力学与岩石工程研究所所长Heinz Koniezky教授。在Heinz教授的带领下，共同参观了研究所的实验室，并就一些具体的岩石试验问题进行了探讨。弗莱贝格工业大学岩石力学与岩石工程研究所拥有世界顶尖的试验设备（图3），本次访问团队成员受益良多。

On July 25,2025, team leader Wang Suran and member Li Yi visited Professor Heinz Koniezky, Director of the Institute of Rock Mechanics and Rock Engineering at Germany's Freiberg University of Technology. Under Professor Koniezky's guidance, they toured the institute's laboratories and engaged in discussions about specific rock testing challenges. The institute is equipped with world-class experimental facilities (Figure 3), and the visit proved highly beneficial for the team members.
