| 摘 要： | 针对目前《建筑物地基基础设计规范》中介绍的“规范法”在手动计算多个独立基础相互影响下的地基沉降量时，“规范法”查表工作量大且效率低．文章在对地基沉降计算公式进行分析和进一步推导后，提出一种修正后的应力面积法，即利用求解多个基础荷栽在地基中产生的叠加后总附加应力面积与地基土压缩模量的比值来计算地基沉降量．结果表明：这种方法可以省掉大量的附加应力系数查表工作，提高计算效率，可以在计算地基沉降量问题中得到应用，但精度略低．

| Abstract: | Aiming at shortages of ＂standard method＂ introduced in Code for Design of Building Foundation, which costs a lot of work to look up tables in the settlement calculation of multiple foundations, this paper proposes a modified additional stress area method by calculating the ratio between the distribution area of total additional stress under multiple foundations and the compression modolus of the ground after analyzing and deducing the calculation formula of settlement. The conclusion is that this method only costs a little work on looking up additional stress coefficient tables and can improve the computational efficiency. It is much useful and can be extensively applied in hand calculation of multiple foundation, except its poorer accuracy. |
