上海地区地下水位回升对地下室底板受力影响研究

Study on Effect of Groundwater Level Rise on the Stress of Basement Floor in Shanghai

以上海地区某工程为背景,开展了地下水位回升对地下室底板受力影响的研究。研究结果表明,地下水位回升极有可能对地下室底板受力造成不利的影响,故在结构设计时就必须采用能够充分考虑水土耦合作用及土体时空效应的计算模型,以免造成严重的地下室结构破坏事故。

Based on a project in Shanghai, the effect of groundwater level rise on the stress of the basement floor is studied. The results show that the rise of the groundwater level is likely to have adverse effects on the stress of the basement floor. Therefore, it is necessary to adopt the calculation model which can fully consider the coupling effect of soil and water and the space-time effect of the soil in the structural design to avoid serious damage accidents of the basement structure.
