坡形地貌回填土对地下室结构影响分析

Influence Analysis of Backfill with Slope Topography on Basement Structure

现阶段设计过程中,对于坡地建筑,主要是验算其稳定性和抗滑移性能。一般情况下,不考虑回填土状态对整个结构倾覆的影响。从考虑回填土状态对结构倾覆的角度出发,提出相应的计算公式,并以某重点工程为例,验算了结构在不同回填工况下的基底承受的最小应力,确保结构安全。

The checking calculation of the stability and anti-sliding performance of slope construction is important in design stage. The effect of backfill condition on the whole structure overturning is not considered in general case. This paper puts forward relevant calculation formula by considering the effect of backfill condition on the whole structure overturning,checks the minimum bearing capacity of the basement in different backfill conditions based on some key project,which ensures the structure safety.
