1、砖基础大放脚工程量计算公式等高式大放脚折算面积=0.126*（层数+1）*0.0625*层数不等高式大放脚折算面积（高低层数相同时）=【0.126*（高步数+1）+0.063*低步数】*0.0625*步数不等高式大放脚折算面积（高低层数不同时）=（0.126*高步步数+0.063*低步步数）*0.0625*（步数+1）条形砖基础工程量可用下式计算：基础体积=墙厚x（设计基础高度+折加高度）x基础长度■柱及地梁体积砖基础大放脚的折加高度是把大放脚断面层数，按不同的墙厚折成高度，也可用人放脚增加断面积计算。为了计算方便，将砖基础人放脚的折加高度及大放脚增加断面积编制成表格。计算基础工程量时，
