方形群桩基础软弱下卧层顶面附加应力的简化计算

Simplification Calculation of the Additional Stress on Top Surface of the Weak HorizonatalSub-foundation Under Square Grouped Piles Foundation

从群桩基础计算理论的角度出发,以方形群桩基础软弱下卧层顶面附加应力设计值的计算进行了研究,结果表明,采用本文提出的简化计算方法要比现有理论的计算方法简单,其计算结果相同。

From the view-point of grouped piles foundation calculation theory, this article has studied the calculation of design value of additional stress on top surface of the weak substratum undes square grouped piles foundation. The result shows that the simplified calculation method as proposed by this article is simpler than the calculation method of present theory, but giving the same answer.
