| 摘 要： | 利用Ｍｉｎｄｌｉｎ竖向附加应力公式，通过积分得到地基内矩形面积上三角形分布荷载作用下角点下竖向附加应力解析式，并通过对地基内矩形面积上均布和三角形分布载荷作用下角点下竖向附加应力公式关于深度进行积分，得到了计算角点下竖附加应力面积的解析式，根据解析式制表格，可供运用应力面积法进行群桩实体基础等的最终沉降计算时查用。

| Abstract: | Based upon Mindlin' s formula for vertical superimposed stress, through integration, an analytic expression to compute the vertical superimposed stress under comer points of rectangular area under triangularly distributed loading in problem of pile foundation is obtained. In addition, in order to use the stress area method to compute the final settlement of pier foundation, the analytic expression of superimposed stress area under corner points of rectangular area due to uniformly and triangularly distributed load are also obtained by integration. |
