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 e-rosion of the pile foundation caused by the groundwater,damage of underground structure caused by the groundwater fluctua-tion,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 de-sign 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 be-tween the components in the design will have a satisfactory effect on the practical engineering analysis.
