地下建筑抗浮失效案例分析及处理

Analysis on Failure Anti-floating Case of Underground Buildings and its Countermeasure

通过工程实际案例的不良地下水对地下建筑抗浮失效的案例分析与研究,阐述简单的地下水类型转化形成复杂的不良地下水类型的全过程,及不良地下水对地下建筑抗浮失效的原因,探求对不良地下水的防治与对策。针对地下建筑抗浮问题,优化地下建筑及其基坑工程勘察、设计、施工;提供明确的地下水类型、合理的抗浮地下水位,使得设计依据充分、施工措施恰当,最终达到地下建筑抗浮有效,使地下建筑工程抗浮安全结果万无一失。

Starting from several special cases study, the effect of unfavorable groundwater on failure anti-float of underground buildings is analyzed to expound the whole process by which a simple groundwater changes to complex unfavorable groundwater, and the reason of effect of unfavorable groundwater on failure anti-float of underground building, reaching after the measures of unfavorable groundwater and anti-float problem, which make it possible to optimize the survey, design and construction of underground building and foundation pit;in the paper, the authors provide definite groundwater types and reasonable anti-floating groundwater level, which is taken to ensure the success of underground buildings anti-floating project.
