在民用建筑框架或承重墙等的设计中，经常会遇到因柱与柱之间或柱与剪力墙间距离较近造成独立基础相碰或重叠的问题。解决方法是在柱下组成联合基础。本文试用简化设计方法进行计算，结果可靠。设计方法中还考虑了安全、经济、施工方便等因素 In the design of civil building frameworks or load-bearing walls, it is often encountered that the independent foundations collide or overlap due to the distance between the column and the column or between the column and the shear wall. The solution is to form a joint foundation under the column. This article tried to simplify the design method for calculation, the result is reliable. The design method also considers safety, economy, ease of construction, and other factors
