摘要
为理解垂直条形均布荷载下地基附加应力公式,文中尝试用角点法,通过叠加求得到矩形面积上均布垂直荷载作用下地基附加应力表达式,然后再根据式中矩形边长的变化情况,推导出垂直均布条形荷载、半无限条形荷载、十字形条形荷载、Z字形条形荷载和无限大面积上均匀满布荷载下的地基附加应力公式,其推导过程体现了有限和无限的辩证关系.
The formula of vertical stress in the vicinity of strip area of foundation with uniform pressure is deduced by superimposing with the method of corner of rectangulow. Furthermore, the formulas of vertical strees in several different areas of foundation with uniform pressure are obtained through changing length of rectangular sides and shape of the area. The process of deduction is helpful to understand the stress on the foundation,and indicates that the finiteness can be changed into infiniteness mutually.
