1提出问题在混合结构横墙多的中低层建筑中，其条形基础宽度设计一般均按线荷载计算，计算中较易忽视纵、横墙交接区域基础底面积的重叠问题，由于基底面积在计算中的重复利用，其得出的基础面积实际上小于上部结构所需要的基础面积，从而就可能使基底应力超过地基容许承载力。
1Problem to be raised In the mid-to-low-rise buildings with multiple horizontal walls of mixed structures, the design of the width of the strip foundation is generally calculated according to the line load. It is easier to overlook the overlap of the base area of the base area of the vertical and horizontal wall, due to the base area In the calculation of the reuse, the resulting base area is actually smaller than the base area required by the upper structure, so that the base stress may exceed the allowable bearing capacity of the foundation.
