砌体结构墙下基础设计的对称修正

Symmetry correction of foundation design under walls with brick masonry structure

砌体结构墙下基础设计时一般按所承受的荷载值计算基础宽度,由于在基础相交处存在重叠问题,应适当调整基础底面尺寸。本文按基础底面压力的分布特点确定基础底面的对称修正范围,得到修正系数的计算公式,方法简捷、结果可靠,便于工程应用。

<Abstrcat>In design of foundation under walls with brick masonry structure, the base width is generally computed according to the loads to which the walls are subjected. Because of the foundation superposition area in cross walls, the sizes of foundation base must be corrected moderately. Based on stress distribution from compressive load in walls, the corrected symmetry size and coefficient formula of foundation base are derived.The simple and practice means can be easily applied in foundation design and construction.
