有软弱下卧土层的基础计算方法

The Basic Calculated Method of Having Soft Bottom Layer

本文给出一种同时考虑持力层及软弱下卧层的承载力,通过一次计算即得出条形基础或矩形基础底面小尺寸的计算方法。这种方法计算有软弱下卧土层的基础底尺寸时,既避免了重复验算的工作,又充分利用了软弱下卧层的承载力。

This paper reports a calculation method to get the size of the bottom area of strip and square groundwork by one time calculation,in consideration of the support force of both holding-force layer and soft bottom layer. For the calculation of bottom size with soft bottom layer,this method not only save the labor of repeat checking computations,but also sufficiently make use of the support force of soft bottom layer.
