摘要
以某地下室上浮破坏案例为背景,首先借助弹性力学的薄板弯曲理论推导出地下室底板的挠度表达式,并通过表达式计算地下水位位于地下室底板以上的12种情况下的地下室底板最大挠度,并列举9.5 m、6.5 m、15 m的三种情况下的地下室底板最大挠度,然后依靠ABAQUS软件分别对地下水位位于地下室底板以上的12种情况进行数值模拟,选取其中9.5 m、6.5 m、15 m的三种情况进行分析,并将理论推导结果与数值模拟结果进行比较,以此来验证这一理论推导公式的合理性,最终验证了公式推导较为合理。最后根据分析结果提出3种关于地下室底板上浮破坏的防治措施。
Based on the case of the uplift failure of the basement of Fushun Xinglong Moore Sports Mall, this paper firstly derives the deflection expression of the basement floor by means of the elastic plate bending theory, and then the ABAQUS was adopted to separately locate the groundwater level above the floor of the basement by 9.5 m and 6.5 m. The numerical simulation is carried out in three cases of 15 m to verify the theoretical derivation formula, and the theoretical derivation results are compared with the numerical simulation results. Finally, based on the analysis results, four kinds of prevention and control measures for the floating damage of the basement floor are proposed.
