在实际工程中,常常需要计算偏心荷载作用下园形面积基础对相邻基础沉降影响。在现有文献中,园形面积三角形荷载情况土中应力系数,只有园周上压力为零和最大点的公式(或表格)。本文列出积分式並运用电子计算机,对园形面积上三角形荷载分布情况地基中的任意点垂直应力进行数值积分求得结果。园形面积三角荷载的土中垂直应力公式,可由布辛奈斯克公式积分求得。将座标原点放在园周压力为零的点上,x、y、z座标方向参见图1。
In practical projects, it is often necessary to calculate the influence of the base area on the settlement of adjacent foundations under eccentric loads. In the existing literature, the stress coefficient of the soil in the circular area of the triangular area is the formula (or table) of the zero pressure and the maximum pressure at the circumference of the circle. This article lists the integral type and uses an electronic computer to obtain the results by numerically integrating the vertical stress at any point in the distribution of triangular loads on the circular area. The formula for the vertical stress in the soil with a triangle-shaped load on the circular area can be obtained from the integral formula of the Buskinske. Place the coordinate origin at the point where the pressure is zero around the circle. See Figure 1 for the x, y, and z coordinates.
