斜坡上地下室抗浮设计的数值分析

Numerical Analysis of Anti-floating Design of Basement on Slope

位于斜坡上的地下室周边地势标高相差较大,难以用一个统一的抗浮设防水位来进行抗浮设计。作者根据某工程实例基于三维稳定流基本方程,根据周边地形,采用数值计算方法,计算底板孔隙水压力,为分区确定地下室抗浮水位提供依据,可为类似工程提供参考。

Basement on the slopes,because terrain elevation difference is obvious in the surroundings,it is difficult to use a unified fortification of anti-uplift water level for anti-floating design. Based on the basic equation of the three-dimensional steady flow,the author takes a practical project as an example,uses the numerical calculation method to calculate the pore water pressure of the bottom plate,provides the basis for determining the anti-floating level of the basement,which can provide a reference for similar projects.
