GMS软件技术在某市地下轨道交通工程抗浮设防水位确定中的应用

Application of GMS software in the determination of anti floating water level of underground rail transit project

抗浮设防水位即建筑物运营期间的最高水位,我国相关规范中将历时实测最高水位或工程勘察期间的最高稳定水位定义为建筑物的抗浮设防水位。在地下轨道交通工程领域,按规范确定抗浮设防水位准确度不高,现阶段,国际上普遍采用由美国开发的最先进的综合性地下水模拟软件GMS进行抗浮设防水位确定,该软件具有较好的使用界面、强大的前后处理功能及三维可视效果。本次研究采用GMS软件技术对某市地下水位进行数值模拟,预测极端条件下地下水水位变化,最终确定抗浮设防水位,从而为工程设计提供科学依据。

Anti floating water level is the highest water level during the operation of the building. In our country,the maximum stable water level during the period of the highest water level or the period of engineering investigation is defined as the anti floating water level of the building in China＇s relevant norms. In the field of underground rail transit engineering,according to the standard the anti floating water level is not accurate. At the present stage,the international advanced groundwater simulation software-（ GMS） is widely used in the world to determine the anti floating water level. The software has a good interface,powerful functions and 3 D visualization. By using GMS software to simulate the groundwater level of a city this study predicted groundwater level change under extreme conditions and determined the anti floating water level finally,thus it provided scientific basis for engineering design.
