摘要： 为研究地下水位变化对高层建筑地下结构损伤的影响，从地下水对桩基的侵蚀、地下水上升对地下结构损伤问题、地下结构沉降问题、地下结构系统协调变形问题方面进行了梳理总结。结果表明：①地下水位变动对地下结构的影响，如地下水位上升后水位恢复过程等，还需要投入更多的相关实验和模拟研究；②对地下室合理设计，及时减轻地下水位上升造成的影响；③地下水位变化会造成地基发生沉降，使得地下结构出现不规律变形；④设计中考虑构件之间相互作用会对实际工程计算产生良好的效果。

Abstract: To study the influence of the variation of the groundwater level on the damage of high-rise building substructures, this paper investigates potential factors. Throughout the literature review and comparative analysis, this paper presents the erosion of the pile foundation caused by the groundwater, damage of underground structure caused by the groundwater fluctuation, the settlement of the underground structure and coordinated deformation of underground structure system. The results show that: (1) the finite element analysis of the variation of the groundwater level on the underground structure, such as water level withdrew process after the groundwater level rise, needs further experimental and simulation studies; (2) reasonable design of basement, timely reduce the impact of rising groundwater level; (3) The variation of the groundwater level will cause the settlement of the foundation and irregular deformation of the underground structure; (4) considering the interaction between the components in the design will have a satisfactory effect on the practical engineering analysis.

Key words: Underground Structures, Groundwater Level, Basement, Finite Element
