| 摘 要： | 矩形基础受垂直均布荷载作用下,地基土中任一点的附加应力虽然可以通过角点法和应力叠加原理求得,但是除了矩形角点下各点计算较容易外,其余的点计算均较繁琐;矩形基础受垂直三角形分布荷载作用下,矩形基底面积垂直投影范围内地基土中各点的附加应力虽然可以通过角点法和应力叠加原理求得,但是除基底荷载分布为零的边的角点下各点计算较容易外,其余的点计算都很繁琐,而矩形基底面积外的点则无法计算。本文通过推导得出两个公式,借助电脑,能很容易地计算矩形基础受垂直荷载作用下地基土中任意点的附加应力系数,并通过计算对比,验证了公式是正确的。

THE FORMULA FOR THE VERTICAL ADDITIONAL STRESS COEFFICIENT OF THE ARBITRARY POINT OF THE FOUNDATION SOIL WHILE THE RECTANGULAR FOUNDATION SUBJECTED TO THE VERTICAL LOAD |

| Abstract: | While the rectangular foundation is subjected to the vertical load,though the additional stress of the arbitrary point of the foundation soil can be calculated through the Angular-point Method and Principle of Superimposed Stress,the calculation is complicated and minute except for those points at the axes which are vertically through the angular points of the rectangle.While the rectangular foundation is subjected to the vertical triangular distribution load,though the additional stress of those points in ... |
